Foundations of Value Engineering
You will learn
- What value really means — and the one equation behind the whole discipline
- The five legitimate ways to improve value
- VA vs. VE vs. VM, and the four types of value
- Why VE beats ordinary cost-cutting, every time
1.1 · Value is a ratio
Everything in this course rests on one equation: Value = Function ÷ Cost. Function is what the product must do — its performance, reliability and appeal. Cost is everything it takes to deliver that function across the lifecycle. A product is not "expensive" or "cheap" in isolation; it is good or bad value relative to the function it delivers. Value Engineering is the discipline of improving that ratio deliberately.
The method was born at General Electric in 1947, when Lawrence D. Miles noticed that wartime material substitutions — forced by shortages — often produced parts that worked better and cost less. His insight: teams had been buying parts when they should have been buying functions. Ask "what does it do, and what else could do it?" and whole design spaces open up.
1.2 · Five ways to improve value
- Same function, lower cost — classic cost-out (most VAVE work lives here)
- More function, same cost — value-up for competitiveness
- More function, lower cost — the VE ideal; happens more often than you'd think
- Function grows faster than cost — justified premiumisation
- Trim unvalued function, cut cost sharply — data-backed de-contenting
Note what is not on the list: cutting function customers value to save cost. That is how cost-cutting destroys brands — and it is precisely what the function-first method prevents.
1.3 · VA, VE and VM
Value Analysis (VA) applies the method to products already in production — teardown, question, re-engineer, implement as running changes. Value Engineering (VE) applies it during design, before cost is locked in — and since roughly 80% of lifecycle cost is committed by early design decisions, a euro of effort in design returns what ten return later. Value Management (VM) is the governance layer that makes both permanent: targets, funnels, cadence, capability. Together the practice is called VAVE.
1.4 · The four types of value
- Use value — what the product does; its work-performing functions
- Esteem value — what makes it desirable: brand, finish, perceived quality
- Exchange value — what it can be traded for: price power, resale
- Cost value — the sum of material, labour, overhead and lifecycle cost
Esteem value is real value — customers pay for it. The VE question is never "kill the chrome"; it is "does this chrome deliver more esteem than it costs?"
1.5 · Value, price and cost — untangling the trio
Three words engineers constantly blur: price is what the market will pay — set by competition and perceived value, largely outside your control. Cost is what you spend to deliver — set by your design and supply choices, largely inside your control. Value is the ratio the customer experiences. The market caps the price; physics floors the cost; everything between is margin plus the headroom VE exists to capture. When someone says "we can't afford that feature", translate it: the function's cost exceeds the price the market pays for it — now it's an engineering problem with three levers, not a budget complaint.
1.6 · Why the economics never stop favouring VE
The cost-commitment curve is the discipline's cornerstone: by the time concept design is frozen, roughly 70–80% of lifecycle cost is committed while less than 10% has actually been spent. Every later phase can only optimise inside decisions already made — which is why an hour of function analysis at a design gate outperforms a month of price negotiation after tooling kick-off. Add the arithmetic of scale: a study costing a few person-weeks that removes even 5% from a high-volume product returns its cost hundreds of times over. This is why VE is one of the few methodologies written into law: US federal agencies are required to apply it (OMB Circular A-131), and federal-aid highway projects above statutory thresholds must undergo VE analysis before construction approval.
Worked example
A commodity kettle and a premium kettle both heat water identically. The commodity unit costs €9.80 to make; a rival's equivalent costs €12.40 — same functions, higher cost, so lower value. The premium kettle costs €18 but adds real esteem value customers pay €35 for — higher value too. Value judges the ratio, not the price tag.
Case study — documented
From wartime shortage to a billion a year. The discipline's origin is documented: at General Electric in 1947, Lawrence Miles' team, forced by shortages to substitute materials, kept finding the substitutes performed better for less — and turned the accident into a method. The modern proof of scale is public record: on the US federal-aid highway programme alone, VE studies delivered an average of $1.7 billion per year of implemented savings from 2002–2011 — with $1.0 billion in FY2011 from 378 studies and 1,224 implemented recommendations. Source: FHWA Value Engineering annual summary reports (fhwa.dot.gov/ve).
Common pitfalls
- Treating VE as a euphemism for cheapening — the method is defined on protecting function
- Running it once and declaring victory — savings compound only with cadence
- Leaving it to purchasing alone — 70–80% of cost is committed in design, out of purchasing's reach
- Skipping function analysis and jumping to ideas — that's a brainstorm, not VE
Key takeaways
- Value = Function ÷ Cost. Engineer both sides, never blindly cut one.
- VE (design) has ~10× the leverage of VA (production) — but both pay.
- Function-first thinking is what separates VE from a discount hunt.
Now do it — hands-on assignment
Pick any household product on your desk right now. Write its basic function (verb + noun) and five secondary functions. Then ask of each: is this a requirement, or just how this design happens to work?
Pre-Workshop Preparation
You will learn
- How to scope a study and set a defensible savings target
- Who belongs on the team — and who kills it
- The data pack that makes or breaks the workshop
2.1 · Scope and sponsorship
Every failed VE study fails before it starts. Preparation takes 2–4 weeks and begins with a sponsor — someone senior enough to commit resources and act on decisions — plus a written scope: which product, which cost baseline, what target (typically 10–20% of the addressed cost), what's explicitly out of bounds. An unscoped study wanders; an unsponsored one produces slides.
2.2 · The team
Six to ten people, cross-functional by design: design engineering, manufacturing, purchasing, quality, finance, service — plus key suppliers for commodity insight. Homogeneous teams produce homogeneous ideas; the friction between functions is where the ideas live. The team is led by a trained facilitator who owns the process, not the content — ideally certified (VMA/AVS/CVS, covered in Module 12).
2.3 · The data pack
- Costed BOM — every part with material, process, labour and overhead cost, validated by finance. This is non-negotiable.
- Quality history — warranty Paretos, scrap and rework data, field-failure modes
- Voice of customer — requirements, satisfaction data, feature-usage evidence
- Volumes & forecasts — because every lever's economics depend on quantity
- Competitor samples — procured early; teardown insight feeds every phase
- Physical parts — the actual product in the room. Teams ideate on what they can touch.
2.4 · Choosing the right first product
Programmes live or die on the first study's credibility, so pick the target deliberately. Score candidates on: spend (annual volume × unit cost — enough zeros to matter), design authority (you can actually change it), stability (2+ years of production life left to harvest savings), pain (margin pressure or warranty trouble creates pull), and data (a costed BOM exists or can be built in two weeks). A mid-complexity, high-volume product your own engineers designed is the ideal first target; the flagship with frozen tooling and a defensive chief engineer is the worst.
2.5 · Roles that make or break the study
- Sponsor — owns the target, attends kick-off and Phase 6, clears roadblocks. No sponsor, no study.
- Facilitator — owns the process and the clock; deliberately NOT the deepest product expert (experts defend designs).
- Finance partner — validates the baseline and every savings claim; involving them from day one prevents the classic "those numbers aren't real" ambush in Phase 6.
- Idea champions — assigned per surviving idea in Phase 4; they carry proposals through development.
- Scribe — captures every idea verbatim with its function tag; memory is not a capture system.
2.6 · Freeze the baseline, then set the target
Before the workshop, freeze a dated cost baseline — a specific BOM revision, volume basis and currency — and agree the measurement rules (gross vs. net, how commodity swings are neutralised). Savings claimed against a moving baseline convince no one. Then set the target from evidence: a benchmark gap, a margin requirement, or the value-mismatch total from a prior scan — not a round number pulled from the ceiling.
Worked example
Scope statement, washing-machine drum unit study: "Reduce works cost of drum assembly (baseline €38.20/unit, validated 12 May) by ≥12% within 9 months. In scope: drum, spider, bearings, seals, counterweights. Out of scope: motor (separate programme), safety-critical fastener grades. Sponsor: VP Engineering. Team: design, mfg, purchasing, quality, finance + bearing supplier." One paragraph — and every argument the workshop will have is already settled.
Case study — documented
Preparation, mandated by law. US federal-aid highway projects above statutory cost thresholds are required to undergo VE analysis before construction — studies must be scoped, staffed and completed at defined project milestones. That enforced preparation discipline is a large part of why the programme reliably banks nine-figure savings year after year rather than depending on heroics. Source: 23 U.S.C. §106(e) / FHWA VE regulations (23 CFR Part 627).
Common pitfalls
- Starting without a sponsor who can actually decide
- A team drawn from one function — homogeneous teams produce homogeneous ideas
- Walking in with an unvalidated BOM (the workshop becomes an argument about the baseline)
- Scoping 'the whole product' — unbounded scope means unbounded shallowness
- Setting targets by decree with no evidence behind them
Key takeaways
- 2–4 weeks of preparation; a validated costed BOM is the entry ticket.
- Cross-functional team of 6–10 with a facilitator who owns process, not content.
- No sponsor, no study — decisions need someone empowered to make them.
Now do it — hands-on assignment
Draft a five-line scope statement for a product you know well: baseline cost, target %, in scope, out of scope, sponsor. Use the pre-workshop checklist in the SAVE Workshop Agenda template.
Phase 1 — Information
You will learn
- Miles' founding questions and why they still work
- How to build the cost baseline the whole team trusts
- Pareto thinking: finding where the money hides
3.1 · Know the thing cold
The Information Phase assembles the complete picture before anyone proposes anything. Miles' founding questions structure it: What is it? What does it do? What does it cost? What is it worth? What else could do the job? The discipline of answering the first four before touching the fifth is what separates a SAVE study from a brainstorm.
3.2 · The cost walk
Walk the costed BOM as a team: material, conversion, labour, overhead, logistics, warranty. Then Pareto it — typically 20% of parts carry 80% of cost, and those parts get the analytical firepower. Complement with a process walk: visit the line, watch the assembly, time the operations. Cost that looks reasonable on a spreadsheet often looks absurd on the shop floor.
3.3 · Requirements, not assumptions
Capture what customers actually require — via QFD, Kano analysis or plain structured interviews — and tag each requirement as must-have, performance, or delighter. Later, when someone claims "customers need this", the team checks the evidence, not the volume of the voice.
3.4 · Structuring cost data so it talks
A costed BOM answers "what does each part cost?" — but the Information Phase needs "why does it cost that?" Split every part into material / conversion / labour / overhead, and be suspicious of allocated overhead: standard-costing systems smear indirect cost by labour hours or material value, which can make a simple part look expensive and an expensive process look cheap. Compute cost density metrics — €/kg against material benchmarks, € per function against the worth estimates coming in Phase 2 — because density exposes outliers that absolute Paretos hide.
3.5 · The Kano model in five minutes
- Must-be — expected silently (brakes work). Absence enrages; excellence earns nothing. Deliver at minimum adequate cost.
- Performance — more is better, linearly (fuel economy, capacity). Customers consciously trade money for these — spend here matches price.
- Attractive — unexpected delighters. High esteem-value leverage, but validate with data before spending.
- Indifferent — customers genuinely don't care. The prime de-spec hunting ground.
- Reverse — some customers actively dislike (complexity, extra buttons). Removing these raises value while cutting cost — the perfect VE move.
Mapping requirements to Kano categories converts the vague instruction "don't hurt the customer" into a surgical one: protect must-be and performance, interrogate attractive, attack indifferent and reverse.
Worked example
A 220-part BOM was Pareto-ranked: the top 18 parts carried 78% of cost — the study focused there. The process walk found an operator hand-deburring every housing, a step that existed in no routing and no cost model: 40 seconds of labour per unit, invisible on every spreadsheet, found only by walking the line.
Case study — documented
Information phase at its purest: the Tata Nano. The price was fixed first — ₹1 lakh (~$2,500), announced publicly — and the entire information phase worked backwards from it: a target cost near ₹65,000, every requirement interrogated against what rural Indian family mobility actually required. The outcome decisions (one windscreen wiper, three wheel lugs, no radio, adhesives over welding, rear engine) were only possible because the team first established, with data, which functions the customer valued — and which they didn't. Source: published target-costing case literature on Tata Motors' Nano programme (2003–2008).
Common pitfalls
- Accepting allocated overhead as truth — allocation is arithmetic, not causality
- Surveying opinions instead of observing usage — customers' behaviour beats their words
- Skipping the line walk — spreadsheets hide what floors reveal
- Letting the loudest requirement (not the evidenced one) set the spec
Key takeaways
- Information is ~20% of workshop effort — never skip or compress it.
- Deliverable: a validated cost & requirement baseline, Pareto-ranked.
- Touch the product, walk the line — spreadsheets hide what floors reveal.
Now do it — hands-on assignment
List your product's ten biggest parts and guess-rank their cost. Now find real numbers for the top three — how wrong were you? That gap is why the Information Phase exists. Capture it in the Function–Cost Matrix worksheet (Step 1).
Phase 2 — Function Analysis & FAST
You will learn
- Writing functions as verb–noun pairs, and classifying them
- Building a FAST diagram with scope lines
- The function–cost matrix, worth, and the Value Index
4.1 · The heart of the method
This phase is what makes VE, VE. Every element of the product is expressed as a two-word verb + noun function: "transmit torque", "resist corrosion", "convey esteem". Two words only — if you need more, you are describing a solution, not a function. The abstraction is the point: "fasten flange" locks you into bolts; "join components" opens welding, adhesives, snap-fits and integration.
4.2 · Basic vs. secondary
The basic function is why the product exists — remove it and the product is pointless (a kettle's basic function is heat water). Secondary functions are how this particular design happens to work — and that is where most removable cost hides, because secondary functions are design choices, not requirements. All-time functions (ensure safety, convey esteem) act across the whole product and are drawn above the main path.
4.3 · The FAST diagram
Function Analysis System Technique maps function logic on one axis: moving right answers HOW? a function is achieved; moving left answers WHY? it exists. Dashed scope lines bracket the study: the higher-order objective sits outside the left line, assumed functions (like "supply power") outside the right. A FAST diagram that reads correctly in both directions is validated logic; one that doesn't reveals the team never really understood the product.
4.4 · Function–cost matrix and the Value Index
Now load economics onto the logic. Allocate every part's cost across the functions it serves — rows sum to component cost, columns to function cost. Then estimate each function's worth: the lowest cost that could still reliably achieve it, benchmarked against the cheapest known way in any industry. The Value Index = Cost ÷ Worth ranks the mismatches:
- VI ≤ 1.2 — healthy; leave it alone
- VI 1.2–2.0 — watch list; challenge opportunistically
- VI > 2.0 — attack; this function is a creative-phase target
Example: a kettle's "indicate status" function costing €0.60 against a €0.15 worth (a simple neon lamp achieves it) has VI = 4.0 — a €0.45-per-unit opportunity found by arithmetic, not opinion. Multiply by a million units and this one row funds the whole study.
4.5 · Writing verb–noun pairs that actually work
Use an active, measurable verb and a measurable noun: "transmit torque", "conduct current", "limit temperature". Ban the weasel verbs — provide, allow, enable, facilitate — they smuggle solutions in and measure nothing ("provide mounting" is a bracket in disguise; "position component" is a function). The acid test: could two engineers independently agree how to measure whether the function is performed? If not, rewrite it.
4.6 · The full function taxonomy
- Basic — the reason the product exists. Exactly one per scope, or your scope is wrong.
- Secondary — how this design happens to achieve the basic function. The main cost pool.
- Required secondary — imposed by regulation or codes ("suppress interference", "resist flame"). Non-negotiable in existence, fully negotiable in how.
- Esteem — functions of desirability ("convey quality"). Real value; measure with market data.
- Unnecessary — supports nothing on the FAST path. Pure gold: delete without loss.
- Higher-order / assumed — outside the scope lines left and right; they anchor the logic but aren't studied.
4.7 · Building the FAST diagram, step by step
- 1. Write every function on a card (random function determination — no order yet).
- 2. Find the basic function; place it just inside the left scope line.
- 3. For each card ask HOW is this achieved? — its answer sits to its right; WHY does it exist? — to its left.
- 4. Where one function is achieved by several together, stack them vertically (AND); alternatives branch (OR).
- 5. Hang all-time functions (ensure safety, convey esteem) above the main path; one-time functions (facilitate assembly) below.
- 6. Draw the scope lines; the higher-order objective sits outside-left, assumed functions outside-right.
- 7. Read the whole diagram aloud in BOTH directions. Any sentence that sounds wrong is a misplaced card.
Note there are two flavours: the technical FAST above, and the customer FAST, which starts from customer-need verbs (assure convenience, assure dependability) — useful when the study scope is a whole product rather than a subsystem.
4.8 · Estimating worth without fooling yourself
Worth is the study's moral compass, so estimate it honestly, four ways: (1) cheapest existing solution — the lowest cost any industry pays to achieve this function (a neon lamp indicates status for €0.15, whatever your current PCB does); (2) physics floor — minimum material and energy the function fundamentally requires; (3) historical best — the cheapest your own company ever achieved it; (4) expert triangulation when data is thin. Always function-level, never part-level, and always with the assumption written down. Worth set equal to current cost is the classic self-deception — it guarantees every VI equals 1.0 and the study finds nothing.
Worked example
Validate FAST logic both ways: "WHY do we generate heat? — to heat water. HOW do we heat water? — by generating heat." Reads correctly in both directions → the logic holds. Now the matrix: "indicate status" carries €0.60 of cost but a neon lamp achieves the function for €0.15 — VI 4.0. At 1M units/year, that single row is a €450k/year opportunity, found with arithmetic.
Case study — documented
Where FAST came from. Function analysis existed from Miles' first studies, but the diagram that made function logic testable was created in 1965 by Charles W. Bytheway, an engineer at Sperry Rand UNIVAC, who presented the Function Analysis System Technique at that year's SAVE national conference. The HOW→/←WHY double-interrogation he introduced remains the core validation tool of the Value Methodology standard sixty years later — because it converts a debate about opinions into a test any team can run aloud. Source: SAVE International value methodology literature.
Common pitfalls
- Writing solutions dressed as functions ('provide bracket')
- Finding three 'basic' functions — that's three scopes, not one
- Setting worth equal to current cost, guaranteeing the study finds nothing
- Chasing decimal-perfect cost allocation — bands beat false precision
- Skipping the read-aloud in both directions — unvalidated logic propagates into every later phase
Key takeaways
- Verb + noun, two words — abstraction opens the solution space.
- FAST: HOW→ / ←WHY between scope lines; valid logic reads both ways.
- VI = Cost ÷ Worth; above 2.0 is your target list. VE picks battles with arithmetic.
Now do it — hands-on assignment
Do a full function analysis of a stapler or kettle: functions table, FAST sketch, cost allocation, worth estimate, VI. Print the FAST Diagram Worksheet and the Function–Cost Matrix — 30 minutes, and you'll have run Phase 2 for real.
Phase 3 — Creative Techniques
You will learn
- Osborn's rules and why judgement is deferred
- Six structured ideation techniques and when to use each
- How to ideate on functions, not designs
5.1 · Quantity breeds quality
The Creative Phase generates the maximum number of ways to perform each targeted function — not tweaks to the existing design. Osborn's rules are law: defer all judgement, welcome wild ideas, go for quantity, build on others' ideas ("yes, and…"). A strong workshop produces 200–400 raw ideas; since only about one in eight survives evaluation, volume is not vanity — it is the math.
5.2 · The technique arsenal
- Classic brainstorming — facilitated, time-boxed rounds per function. Fast, social, but vulnerable to loud voices.
- Brainwriting 6-3-5 — 6 people write 3 ideas in 5 minutes, pass the sheet, build on what arrives: 108 ideas in 30 silent minutes; introverts contribute equally.
- SCAMPER — Substitute, Combine, Adapt, Modify/Magnify, Put to other use, Eliminate, Reverse — a mutation checklist for any part or process.
- TRIZ — Altshuller's theory of inventive problem solving: model the contradiction ("stiffer but lighter"), apply the contradiction matrix and the 40 inventive principles distilled from millions of patents.
- Morphological analysis — decompose into sub-functions, list every solution option per sub-function, recombine columns into thousands of concept permutations.
- Analogy & biomimicry — how does another industry, or nature, deliver this function for less?
5.3 · AI-assisted ideation
The newest tool in the kit: prime an LLM with the FAST model, the BOM and the constraints, and it will generate and cluster hundreds of candidate ideas in minutes — including cross-industry solutions no one in the room has seen. The division of labour is clear: machines diverge, humans judge. AI raises the floor of idea volume; the team still owns feasibility and selection.
5.4 · TRIZ in twenty minutes, not twenty days
TRIZ's core claim, distilled from studying millions of patents: inventive problems are contradictions, and the same ~40 principles resolve them across every industry. A technical contradiction is "improving A worsens B" — stiffer but heavier, faster but hotter. Look up the two parameters in the contradiction matrix and it returns the principles inventors historically used. Example: strength vs. weight of a moving part points to Principle 1 (Segmentation — ribbed or hollow structures), 8 (Anti-weight — counterbalance), 15 (Dynamics — make it adaptive) and 40 (Composite materials). A physical contradiction is "A must be X and not-X" (hot AND cold, present AND absent) — resolved by separation: in time (hot during brazing, cold in use), in space (rigid here, flexible there), or by condition. And the north star is ideality — the Ideal Final Result asks: "how would this function perform itself, with no part, no cost, no harm?" Snap-fits are the IFR of fastening; that question alone generates ideas.
5.5 · The techniques are a toolkit, not a menu
Sequence them: open with brainwriting 6-3-5 (silent, equal, fast volume), move to function-prompted brainstorming to build on the written seeds, apply SCAMPER to the stubborn functions, bring TRIZ when a genuine contradiction blocks progress, and close with analogy rounds ("how does a €2 toy solve this? how does nature?"). Quotas help: "ten more ideas for 'contain water' before lunch" reliably produces eight mediocre ideas and two gems — which is exactly the deal you want.
5.6 · Facilitating for volume
The facilitator's creative-phase job is protecting divergence: enforce the no-judgement rule visibly the first time it's broken (park the criticism on a wall, thank the critic, move on); make the most senior person speak last in every round; run 25-minute sprints with real breaks; and capture every idea verbatim with a function tag — paraphrasing kills the wild ones, and the wild ones stretch the space where the practical winners live.
Worked example
Target function: transmit torque (currently a keyed shaft, VI 2.3). Eight ideas in four minutes of brainwriting: spline, press-fit, taper-lock, polygon shaft, integrated forging, adhesive bond, friction weld, plastic overmould. A TRIZ pass on "stiffer but lighter" adds two more via principle 1 (segmentation: ribbed hollow shaft) and principle 40 (composite material). Ten routes where the drawing showed one.
Case study — documented
Samsung's TRIZ programme. Samsung adopted TRIZ in 1997 and industrialised it: by 2003 it credited the method with around 50 new patents in a single year, and in 2004 one TRIZ-driven project — a DVD pick-up innovation — was reported to have saved over $100 million, with the methodology contributing an estimated $65M+ annually. More than 1,000 engineers were trained in 2004 alone, and TRIZ competence became an expected skill for advancement. Structured creativity, at industrial scale, with a P&L trail. Sources: The TRIZ Journal; Altshuller Institute case reports.
Common pitfalls
- Ideating on parts instead of functions — the incumbent design anchors everything
- Letting the senior voice speak first (anchoring in one sentence)
- Judging ideas in the room — even an eyebrow counts
- Relying on one technique — each opens a different region of the solution space
- Capturing paraphrases instead of the idea as spoken — the wild edges are where the winners hide
Key takeaways
- Defer judgement absolutely — evaluation has its own phase.
- Ideate on the function ("how else to transmit torque?"), never the part.
- Mix techniques: brainwriting for equality, TRIZ for contradictions, AI for volume.
Now do it — hands-on assignment
Solo 6-3-5: take your worst-VI function from the last exercise and write 3 ideas every 5 minutes for 30 minutes — 18 ideas minimum, no self-censoring. Log them in the Idea Capture Sheet.
Phase 4 — Evaluation
You will learn
- Funnelling hundreds of ideas without killing good ones
- Weighted matrices, Pugh analysis and effort–impact
- Building implementation scenarios with champions
6.1 · Coarse screen first
Never deep-analyse 300 ideas. First pass is go / grow / park: clearly feasible ideas advance, promising-but-immature ones get grouped and strengthened, and the rest are parked (never deleted — parked ideas seed future waves). This typically cuts the list by two-thirds in an hour.
6.2 · Structured ranking
Survivors get scored on weighted criteria — savings potential, technical risk, investment, time-to-implement, customer impact. The weighted evaluation matrix makes trade-offs explicit; the Pugh matrix compares concepts against the current design (the datum) with simple +/−/S scores, ideal for concept selection; the effort–impact grid sorts quick wins from strategic projects.
6.3 · Scenarios and champions
Ideas interact — a material substitution may enable a process change that unlocks a part integration. Cluster compatible ideas into implementation scenarios, and give every surviving idea a champion: a named owner who carries it into development. Ideas without owners are opinions.
6.4 · Designing evaluation criteria that don't lie
Four to six criteria, agreed with the sponsor before anyone sees the idea list — criteria chosen after seeing ideas get bent toward someone's favourite. Watch for double counting: "annual savings" and "payback" both measure money; pick one plus investment. A workable default: net savings (40%) · technical risk (30%) · time-to-implement (20%) · investment (10%), with finance owning the savings scale so Phase 6 can't be ambushed with "those numbers aren't real".
6.5 · Pugh in practice — a two-minute worked run
Datum: the current keyed shaft. Candidates: spline, polygon shaft, plastic overmould. Score each against the datum per criterion as better (+), same (S) or worse (−): the spline runs +cost, +assembly, S-risk, −tooling → net +1; the overmould runs ++cost, −risk, −validation → net 0 but with the biggest upside. Pugh's real power is the second pass: hybridise — can the spline's tooling problem borrow the overmould's approach? Concepts converge upward instead of merely being ranked.
6.6 · From ranked list to executable scenarios
Ideas interact. Run a quick compatibility check (a material substitution may kill a process idea, or enable it), then bundle survivors by implementation vehicle: running changes this year, the mid-cycle refresh, the next-generation platform. Finally the honesty test: count the engineering hours the scenarios need against hours that actually exist. A shortlist beyond your capacity is a wish list — better to implement eight ideas than approve thirty.
Worked example
Two surviving ideas, weighted scoring (savings 40%, risk 30%, speed 20%, investment 10%): Idea A — spline shaft: scores 8/7/9/8 → weighted 7.9. Idea B — integrated forging: 9/4/3/4 → weighted 5.8. A advances now; B isn't dead — it's clustered into next year's platform scenario, where its tooling investment amortises across three products.
Case study — documented
Eliminate with evidence, not opinion: Toyota's set-based principle. Toyota's product development system — extensively documented by lean-development researchers — deliberately keeps multiple design alternatives alive and eliminates the weakest late, with test data, rather than betting early on one concept. The VE Evaluation Phase encodes the same philosophy at workshop scale: coarse screen first, structured comparison against a datum (Pugh), convergence by hybridising — and no idea killed on taste alone. Sources: Ward, Sobek et al., studies of Toyota set-based concurrent engineering.
Common pitfalls
- Scoring theatre — criteria reverse-engineered to crown a favourite
- Judging by this year's tooling budget (park it for next-gen instead of killing it)
- Ranking ideas independently and missing their interactions
- Leaving evaluation without named champions — unowned ideas are already dead
Key takeaways
- Screen coarse, then rank structured — don't deep-dive 300 ideas.
- Pugh compares vs. the current design; weighted matrices make trade-offs explicit.
- Roughly 1 in 8 raw ideas survives into development — and that's healthy.
Now do it — hands-on assignment
Score your top six ideas on savings, risk, effort (1–9 each, weighted 50/30/20). Rank them. Notice how the ranking argues with your gut — that argument is the point. The columns are in the Idea Capture Sheet.
Phase 5 — Development
You will learn
- Turning shortlisted ideas into bankable value proposals
- Validation: CAE, FMEA and test planning
- The business-case math: savings, one-time cost, payback
7.1 · From idea to proposal
Champions convert shortlisted ideas into implementable value proposals. Each answers five questions: what exactly changes, what it saves (validated by finance), what it costs to implement (tooling, validation, engineering hours), what could go wrong, and when it lands. An idea with those five answers is a business decision; without them it's still a sticky note.
7.2 · Engineering validation
De-risk before you commit: CAE simulation to verify a thinner wall or relaxed safety factor, design FMEA to expose new failure modes, a DVP&R (design verification plan & report) scaled to the change's risk. For sourcing ideas, a should-cost model or supplier quotation validates the savings claim. Regulated industries add the change-control question early: does this need re-certification, re-validation, PPAP?
7.3 · The business case
The universal arithmetic: annual saving = per-unit saving × volume; payback = one-time cost ÷ annual saving. Most running-change proposals should pay back in under 12 months; well-run VE studies return better than 10:1 overall. Present savings honestly: gross vs. net of implementation cost, and dated — a saving that lands in 18 months is worth less than one landing this quarter.
7.4 · The validation ladder
Match rigour to risk, not to habit: desk calculation → CAE/simulation → rig test → line trial → field pilot. A packaging spec change may need one step; a safety-factor reduction needs all five. Two rules: climb only as high as the risk class demands (over-validation quietly kills payback), and start long-lead items (tooling, supplier qualification) in parallel behind clear kill-gates rather than in series after every test passes.
7.5 · FMEA in ten minutes
Every VE change can create failure modes the current design never had. Score each candidate mode on Severity × Occurrence × Detection (1–10 each; the product is the RPN) — but score the delta against the current design, not absolutes: a thinner wall that raises occurrence from 2 to 4 on a severity-8 mode needs an action; one that goes 2 to 3 on severity-2 needs a note. High-severity or regulated systems escalate to a full cross-functional DFMEA — that's not bureaucracy, it's what makes the saving safe to bank.
7.6 · Money mechanics finance will sign
Net saving = gross piece-cost saving − amortised one-time costs (tooling, validation, engineering hours, scrapped inventory, requalification). Payback = one-time ÷ annual net — the right metric for stable-volume running changes; use NPV at the company hurdle rate when volumes ramp or decay. And date everything: savings start at the implementation date, not the approval date — a proposal without a date has a business case of zero.
Worked example
Idea: replace machined bracket with fine-blanked part. Saving €0.30/unit × 300,000 units = €90k/year. One-time cost: tooling €38k + validation €7k = €45k. Payback = 45k ÷ 90k = 6 months. CAE shows stress margin holds; DFMEA adds one new failure mode (edge condition), mitigated by a die-maintenance interval. Decision-ready.
Case study — documented
Development at giga scale: Tesla's Model Y rear underbody. The idea — replace ~70 stamped and welded parts (as on Model 3) with one or two giant aluminium castings — carried a development case reported as roughly 40% manufacturing-cost reduction for that assembly, large capital avoidance (hundreds of joining robots deleted), and a rear body structure about 30% lighter. It also carried genuine new risks (repairability, casting quality) that had to be engineered and validated before the savings were real — a textbook Phase 5: radical idea, rigorous development, dated implementation. Sources: Tesla statements; Charged EVs / Electrek reporting; Munro & Associates analyses.
Common pitfalls
- Savings estimated by the idea's biggest fan instead of finance
- Forgetting one-time costs (validation, requalification, scrapped stock)
- Validating everything to maximum rigour — over-testing quietly kills paybacks
- No implementation date: an undated proposal has an NPV of zero
Key takeaways
- Five answers make a proposal: what, saves, costs, risks, when.
- Validate with simulation and FMEA — de-risking is what makes savings real.
- Target sub-12-month paybacks; report savings net and dated.
Now do it — hands-on assignment
Build one business case: pick your #1 idea, estimate per-unit saving × annual volume, guess the one-time cost, compute payback in months. If it's under 12, you'd take it to a real board.
Phase 6 — Presentation & Implementation
You will learn
- Selling the study: decision-grade presentation
- The L1→L4 savings funnel and implementation tracking
- Auditing savings against the frozen baseline
8.1 · The decision meeting
Present to the sponsor and decision board: the value logic (functions and mismatches), the numbers (savings, cost, payback), the risks and their mitigations, and the asks (resources, decisions, dates). The output is a decision log — explicit go/no-go per proposal. A presentation that ends without decisions is a rehearsal, not a Phase 6.
8.2 · The savings funnel
Approved ideas enter a staged funnel: L1 Idea → L2 Validated → L3 Approved → L4 Implemented. Each stage has entry criteria (L2 requires finance-verified savings; L4 requires the change in production with PPAP/validation complete). The funnel is reviewed monthly: every idea has an owner, a stage and a date — or it is killed. Savings only "count" at L4, audited against the frozen baseline so inflation and mix changes can't blur the result.
8.3 · Close the loop
Post-implementation, feed the lessons back: update design guidelines, cost standards, preferred-parts lists and the idea bank. This institutional memory is what makes wave two cheaper and faster than wave one — and what eventually turns VE from a project into a capability.
8.4 · The one-pager that wins decisions
Boards decide on one page per proposal: the function and its value mismatch → what changes (picture beats paragraph) → net saving, one-time cost, payback → top risk and its mitigation → the ask, the owner, the date. Then pre-wire: walk the two most sceptical stakeholders through it before the meeting; surprises make executives defensive, and defensive executives say no. The meeting itself produces a decision log — proposal, verdict, owner, date, signature. Applause is not an output.
8.5 · Savings accounting that survives audit
Rules agreed in Phase 0, applied ruthlessly here: measure against the frozen baseline; neutralise commodity and volume swings (index-adjust so a copper spike doesn't erase a real design saving); report the gross → net bridge openly; count only at L4 — implemented in production and audited by finance; and reconcile with purchasing's ledger so the same euro isn't claimed twice. Every credible programme's reputation rests on this paragraph.
8.6 · Closing the loop
Feed every implemented idea back into the system: update design rules (so the next programme never re-adds the deleted bracket), refresh cost standards with the new should-costs, tag the idea bank (parked ideas seed the next wave), and run a 30-minute retro per wave: what stalled, why, and which stage of the funnel leaked. Wave two should always be cheaper and faster than wave one — if it isn't, the loop isn't closing.
Worked example
Funnel snapshot, month 4 of a wave: 320 ideas generated → 118 screened in → 51 validated (L2) worth €2.4M/yr → 31 approved (L3) worth €1.6M/yr → 9 implemented (L4), €410k/yr audited in the P&L. The monthly review killed 12 stalled ideas and reassigned 3 orphaned ones — that discipline is why L4 keeps growing.
Case study — documented
Implementation, audited in public. The FHWA programme doesn't just run studies — it publishes results: in FY2011, 378 studies produced recommendations of which 1,224 were approved and implemented, worth about $1.0 billion in construction savings; the decade average ran $1.7B/yr. The discipline to track recommendation-by-recommendation from proposal to implementation — and to report it annually — is precisely why the numbers are believed. Private programmes should copy the habit, not just the method. Source: FHWA VE annual summary reports.
Common pitfalls
- A brilliant presentation with no decision log
- Claiming savings at approval instead of at audited implementation
- Letting the baseline drift so nobody can prove anything
- Skipping the retro — wave two repeats wave one's leaks
- Hoarding lessons instead of updating design rules and cost standards
Key takeaways
- Phase 6 ends with logged decisions, not applause.
- L1→L4 funnel, monthly review, owners and dates — or ideas die quietly.
- Savings count only in the P&L, audited vs. the frozen baseline.
Now do it — hands-on assignment
Set up the Savings Funnel Tracker with your ideas at L1 — owner, saving, next gate date for each. Diary a 30-minute review for one month from now.
Cost Levers & Should-Costing
You will learn
- The six lever families every programme draws from
- The seven-layer anatomy of a should-cost
- Linear Performance Pricing and fact-based negotiation
9.1 · Six lever families
- Product design — part-count reduction, DFMA, material substitution, tolerance optimisation, de-speccing, platforms, safety-factor right-sizing
- Materials — grade optimisation, recyclates, near-net-shape blanks, nesting & yield, scrap monetisation
- Manufacturing — process substitution, automation, cycle-time/OEE, yield, tooling strategy, make-vs-buy, footprint
- Sourcing — should-cost negotiation, LPP, competitive RFQs, bundling, best-cost-country, supplier VAVE, indexation
- Packaging & logistics — pack spec, returnables, cube utilisation, mode shift
- Complexity & lifecycle — SKU rationalisation, commonality, warranty-cost design
Rule of thumb: where the cost sits decides which family bites. BOM-heavy products (like most automotive) → sourcing + design; labour-heavy → DFMA + automation; volatile-material products → indexation first.
9.2 · Anatomy of a should-cost
A quoted price is one opaque number; a should-cost model decomposes it into negotiable layers: raw material (mass × market price ÷ yield), process & machine (cycle time × machine-hour rate), direct labour, scrap & yield, overhead (driven by plant utilisation), SG&A, and a fair margin. Each layer is built from physics and market rates, and each is a separate conversation with the supplier. Fact-based negotiation with a cleansheet typically recovers 5–15% on quoted prices — without squeezing the supplier's legitimate profit.
9.3 · Linear Performance Pricing
When you buy a family of similar parts, regress price against the dominant cost driver (mass, power, area). Parts above the regression line are paying more per unit of driver than their siblings — a ready-made negotiation target list, produced from data you already own.
9.4 · Building a cleansheet in seven steps
- 1 · Scope — part drawing, material spec, annual volume, sourcing region. Cost is meaningless without these four.
- 2 · Material — net mass ÷ process yield = gross mass, × market price from a commodity index (never a list price).
- 3 · Process route — the operations a competent maker would use, with cycle times from physics and machine specs, not folklore.
- 4 · Machine rate — (depreciation + energy + floorspace + maintenance) ÷ (annual hours × OEE). Utilisation assumptions move this ±30%.
- 5 · Labour — operators per machine × regional loaded wage; automation level is the design variable.
- 6 · Overhead & SG&A — regional percentage benchmarks, sanity-checked; the layer where idle plants hide.
- 7 · Margin — a fair commodity-typical profit. Then sanity-check the total against LPP curves and real quotes.
9.5 · LPP with real numbers
Plot your eight stamped brackets: price (y) against mass (x). Regression: price ≈ €0.85 + €1.9/kg. Six parts hug the line; bracket D sits 18% above it, bracket F 25%. Before celebrating, check specs — F has a special coating (justified); D doesn't (target). One hour with data you already own produced a negotiation list worth more than a month of meetings. That's LPP: cheap, fast, and brutally objective.
9.6 · Negotiation choreography
Never email a cleansheet with "explain the gap" — that's how you get a defensive supplier and a worse relationship. Instead: share the method, invite them to a joint workshop, walk the layers together, and split the conversation three ways — raw material gets indexed in the contract (nobody negotiates the copper price), conversion gets engineered together (cycle times, yields, packaging), margin gets respected. Close with a gain-share clause so their ideas keep coming. Suppliers who feel audited hide information; suppliers who feel partnered volunteer it.
Worked example
Stamped bracket, quoted €1.85. Cleansheet: material €0.62, press time €0.31, labour €0.09, scrap €0.04, overhead €0.22, SG&A €0.08, fair margin €0.06 → should-cost €1.42. The 43-cent gap traced to an outdated steel price and a 55%-utilisation overhead rate. Negotiated to €1.51 with a steel-index clause — supplier keeps a fair margin, buyer stops paying for idle air.
Case study — documented
The founding proof of design-for-cost: IBM's Proprinter. In the mid-1980s IBM applied Boothroyd & Dewhurst's quantitative DFA method to its new printer, benchmarking against the Epson MX-80. The redesign results are the most-cited numbers in the field: parts reduced 152 → 32, assembly operations 185 → 32, assembly time 1,866 → 170 seconds (−91%), with fasteners eliminated entirely via snap-fit architecture. One product, one lever family — and the case that put DFMA into every engineering curriculum. Source: Boothroyd Dewhurst Inc., DFMA case history (dfma.com).
Common pitfalls
- Cleansheeting without process knowledge — physics beats guesswork or it's just a spreadsheet
- Using list prices for materials instead of indexed market prices
- Negotiating the supplier's margin instead of engineering out waste
- Running LPP across parts with non-comparable specs
- Treating negotiation as an event rather than a programme with gain-share
Key takeaways
- Six families; the cost structure tells you which levers bite.
- Should-cost = 7 negotiable layers; negotiate with physics, not percentages.
- LPP finds outliers in your own purchase data — the cheapest savings you'll ever locate.
Now do it — hands-on assignment
Take any purchased part you know the price of. Split it into the seven should-cost layers by rough percentage. Which layer would you challenge first, and with what fact?
Teardown & Competitive Benchmarking
You will learn
- The five-step teardown process
- Six benchmarking dimensions beyond piece cost
- Turning teardown insight into a cost walk to target
10.1 · The five-step teardown
- 1 · Acquire & document — photograph, weigh and measure everything before the first screw turns
- 2 · Systematic disassembly — level by level, capturing time: assembly sequence in reverse is assembly cost in disguise
- 3 · Digital BOM capture — every part logged: material, mass, process, supplier marks, tooling clues, fastener count
- 4 · Should-cost each part — cleansheet the competitor BOM to estimate their cost position line by line
- 5 · Harvest & transfer ideas — side-by-side function comparison feeds the Creative Phase: adopt, adapt or leapfrog
10.2 · Six dimensions of benchmarking
Cost benchmarking is one lens of six: functional (performance per euro — torque/€, lumens/€), design (architecture, integration, material mix), process (how the best plants make it), feature (feature sets vs. price ladders — who over-serves, who under-prices), and patent/IP (expired art you can use freely; active art to design around). Benchmarking also answers VE's hardest question — what is this function worth? — with the best evidence there is: a competitor delivering it for less.
10.3 · The cost walk
Teardown output converges into a cost walk: current cost at the left, target at the right, and quantified lever blocks in between (design −8, material −4, manufacturing −4, sourcing −5, logistics & complexity −2, on a 100 base). Real walks are built bottom-up from validated ideas — each block has owners and dates, or it is decoration.
10.4 · Running a proper teardown lab
You need less than you think: a bench, calibrated scales, torque drivers, callipers, a lightbox with a scale reference in every photo, and — non-negotiable — a data schema agreed before the first screw: part ID, assembly level, mass, material (verified, not guessed), process evidence (parting lines, tool marks), fastener count and type, disassembly time. Photograph every state before changing it. Keep the "wall of parts" — laying both products out side by side, level by level, teaches more in an hour than the spreadsheet does in a week. Scan or CT anything you'll want to measure later; destructive steps are one-way doors.
10.5 · Costing a competitor's BOM honestly
Cleansheet their parts at their assumptions, not yours: their likely region, their volumes, their process choices as evidenced by the parts. Band every estimate (±15% is honest) and document assumptions. The output that matters is the delta table: their door hinge €1.10 vs. yours €2.30 is a finding even if both carry error bars — deltas are robust where absolutes are fragile.
10.6 · Ethics and legality — the bright lines
Teardown of products bought on the open market is lawful, standard industry practice — an entire industry exists to do it. The bright lines: no misappropriated confidential information (a competitor's drawing from a shared supplier is poison — refuse it), and patents are not secrets — they're public documents you should actively read — but copying a patented solution needs a licence or a design-around. Learn freely; copy carefully; involve counsel when adopting, not when analysing.
Worked example
Teardown finding: our door module uses 11 fasteners, 4 clip types and 68 seconds of assembly; the competitor's uses 4 fasteners, 1 clip family and 31 seconds — and their hinge is a two-piece stamping where ours is a machined casting. Three creative-phase targets from one afternoon with a torque driver and a scale.
Case study — documented
Teardown as an industry. Benchmarking is so valuable that a market exists purely to industrialise it: A2MAC1 maintains a database of over a thousand torn-down vehicles that OEMs subscribe to, adding dozens more each year; and Munro & Associates' public Model Y teardown is what surfaced Tesla's rear mega-casting to the wider industry — competitors learned about the biggest body-engineering shift in decades from a third-party teardown. Every product you ship is already someone's open textbook; the only question is whether you read theirs. Sources: A2MAC1; Munro Live / Munro & Associates.
Common pitfalls
- Disassembling before documenting — you get one first teardown
- Costing their parts at your rates and volumes
- Arguing absolutes when deltas are the robust finding
- Teardown tourism: looking at parts without harvesting ideas into the funnel
- Ignoring patents — both as free ideas and as constraints
Key takeaways
- Document before you disassemble — you only get one first teardown.
- Benchmark six dimensions; price alone tells you almost nothing.
- A cost walk without owners and dates is a poster, not a plan.
Now do it — hands-on assignment
Tear down something broken or cheap (an old mouse, a torch). Photograph FIRST. Count parts, fasteners, and estimate assembly seconds. Write down two ideas the designer missed.
Modern & AI-Era Techniques
You will learn
- The 2026 cost-engineering technology stack
- Where AI genuinely accelerates VAVE — and where it doesn't
- How digital tools compress weeks of analysis into hours
11.1 · The digital cost stack
- AI should-cost engines — feature-based tools read 3D CAD, simulate the manufacturing process and output cycle time, tooling and piece cost per region before any supplier quote
- CT-scan & 3D teardown — industrial computed tomography digitises competitor products non-destructively: wall thicknesses, hidden joints, internal architecture
- Spend cubes — classified spend joined with BOM data exposes price variance for identical parts across plants and suppliers
- Generative design & topology optimisation — algorithms explore thousands of geometry variants at minimum material
- Additive manufacturing — part consolidation, tool-less low volumes, conformal-cooled tooling
- Digital twin / CAE — simulation-validated margin removal; virtual DOE replaces physical trials
11.2 · LLMs in the workshop
Large language models now assist across the job plan: mining warranty text and quotes in the Information Phase, generating and clustering ideas in the Creative Phase, drafting business cases in Development, and powering cost knowledge graphs that link functions ↔ parts ↔ costs ↔ suppliers so no lesson is lost between waves. The practical stance: AI compresses analysis and divergence; humans own judgement, validation and decisions. Teams that treat AI output as a starting draft move roughly twice as fast; teams that treat it as an answer ship mistakes faster.
11.3 · What doesn't change
No tool replaces the discipline: functions before solutions, worth before ideas, validation before implementation, P&L before applause. The stack multiplies a good method — it cannot rescue a skipped one.
11.4 · Inside an AI should-cost engine
Feature-based engines work in four stages: geometry extraction (the CAD model is parsed into manufacturing features — holes, bends, bosses, pockets), routing selection (the engine picks a feasible process chain for the material and geometry), physics simulation (cycle times computed from tonnage, melt volumes, tool paths), and regional economics (machine rates, wages and overheads from maintained data libraries — aPriori, for instance, maintains 92 regional cost libraries). Two consequences: quality-in decides quality-out (a sloppy CAD model costs wrongly), and outputs are directional — perfect for ranking design options and preparing negotiations, never a substitute for the final quote.
11.5 · Prompt patterns that work in VAVE
The reliable ideation pattern: role + function + constraints + quantity + ranking — "You are a cost engineer. Generate 25 ways to 'transmit torque' in a 40 Nm automotive application, manufacturable at 200k/year, ranked by likely unit cost; flag any that typically fail durability." Use the same structure to cluster teardown notes, draft business cases, and translate warranty text into function language. Two hard rules: verify every number the model outputs (LLMs are fluent, not calibrated), and never paste confidential BOMs or drawings into public tools — use your company's approved instances.
11.6 · Cost and carbon — one lever, two savings
The same physics that drives cost drives CO₂e: mass, energy intensity, scrap, logistics distance. Add a kgCO₂e column to the cleansheet and most cost levers reveal a carbon dividend — lightweighting, yield improvement, recycled content, nearshoring. With carbon border mechanisms and customer scope-3 reporting spreading, the VE study that quantifies both is answering next year's question this year.
Worked example
Monday: engineer uploads a CAD housing to an AI should-cost engine — 58 seconds later: €4.12 in aluminium die-cast (China rate card), €5.87 (EU). The traditional route — RFQ, three quotes, six weeks — used to be the only way to learn this. The negotiation now starts from physics; the quotes arrive into a prepared mind.
Case study — documented
Minutes versus weeks. Feature-based costing platforms now simulate the manufacture of a CAD model against maintained regional economics — aPriori alone maintains 92 regional data libraries of labour, overhead and machine rates — returning directional should-costs and DFM flags in minutes, against the six-week RFQ loop that used to be the only way to learn a part's cost. The competitive consequence is simple: teams that model before they ask negotiate from knowledge; teams that don't negotiate from hope. Source: aPriori public product documentation.
Common pitfalls
- Treating AI cost outputs as absolutes instead of directional rankings
- Feeding engines dirty BOMs and sloppy CAD, then blaming the tool
- Pasting confidential data into public AI tools
- Automating a method the team hasn't first mastered manually — you can't audit what you can't do
Key takeaways
- CAD-in → cost-out in minutes changes the negotiation game.
- AI diverges and drafts; humans judge and decide.
- Technology multiplies the method — it never substitutes for it.
Now do it — hands-on assignment
Prompt an AI assistant with your function list from Module 4: "Generate 20 ways to [verb noun] for a consumer product, ranked by likely cost." Compare with your 6-3-5 output — what did each source find that the other missed?
Running a VE Programme
You will learn
- Governance: cadence, funnel, KPIs
- Typical savings expectations by maturity
- Professional standards and certifications
12.1 · From event to operating system
One-off studies decay; programmes compound. The operating system: a monthly funnel review (owners, stages, dates), quarterly wave planning (next products, next teardowns), an annual value roadmap per product line tied to margin plans, and continuous capability building. KPIs that keep it honest: funnel coverage (% of product cost under active study, target ≥60%), idea conversion rate, cost transparency (% of BOM with a should-cost, target ≥80%), savings velocity, average payback, and the reuse index.
12.2 · What to expect
A first structured wave on an unworked product typically finds 8–15% of product cost; mature programmes sustain 3–5% annually; study ROI routinely exceeds 10:1. The biggest failure mode is not weak ideas — it is weak follow-through, which is exactly what the funnel governance exists to prevent.
12.3 · Standards and certification
The SAVE International Value Methodology Standard defines the job plan used worldwide; EN 12973 codifies Value Management in Europe. Practitioners certify through SAVE as VMA (Value Methodology Associate — entry level), AVS (Associate Value Specialist) and CVS (Certified Value Specialist — the professional benchmark for leading studies). TRIZ has its own certification levels; both credentials signal a practitioner who runs the method, not just the meeting.
12.4 · Operating models that scale
Three archetypes: a central CoE (deep expertise, tools, standards — but becomes a bottleneck), fully embedded champions in each product line (scales, but skills dilute), and the hybrid that wins in practice — a small central value office owning method, training, tooling and the savings ledger, with certified champions embedded in every line. Report it neutrally: a value office under engineering optimises design and ignores sourcing; under purchasing, the reverse. CFO or COO sponsorship keeps both levers honest.
12.5 · Targets, cascades and incentives
Cascade market-back: product-line margin plans → annual cost roadmaps → subsystem targets at design gates — cost as a spec with the same authority as mass. Incentives need care: reward audited, net, implemented savings (or people will game gross paper numbers), credit idea originators as well as implementers, and never let the savings target exceed the engineering capacity you actually funded — a target without capacity is a morale programme, in reverse.
12.6 · Growing practitioners deliberately
Capability ladders beat hero dependence: awareness (everyone — this course's job) → practitioner (runs analysis in their own product) → facilitator (leads studies; each wave co-facilitated by a learner) → certified specialist (VMA → AVS → CVS through SAVE International). Add a community of practice that meets monthly and an internal "value day" each year where teams present implemented ideas — recognition is the cheapest retention tool a programme has.
Worked example
Programme dashboard, year 2: funnel coverage 64% of product cost · 41% idea conversion · 83% of BOM with should-cost · savings velocity €1.9M/quarter · average payback 8.2 months · reuse index up 11 points. Two facilitators passed AVS this year. That's what "VE as an operating system" looks like on one page.
Case study — documented
Two institutionalisations, one lesson. The US federal government made VE a standing requirement — OMB Circular A-131 (since 1993) obliges agencies to apply it and report annually, and the highway programme's audited $1.7B/yr average shows what mandated cadence delivers. Samsung did the corporate equivalent with TRIZ: training thousands of engineers, making the skill an advancement requirement, and wiring it into development — worth an estimated $65M+ annually by 2004. Different worlds, same lesson: value methods pay when they become how the organisation works, not what it occasionally does. Sources: OMB A-131; FHWA VE reports; The TRIZ Journal.
Common pitfalls
- Running a programme as a spreadsheet of ideas with no cadence or owners
- Setting savings targets without funding the engineering capacity to deliver them
- Letting the central team do everything — it never scales past pilot
- Stopping after wave one, right before compounding starts
- Measuring activity (studies run) instead of outcomes (audited savings)
Key takeaways
- Monthly funnel, quarterly waves, annual roadmap — cadence is the programme.
- 8–15% first wave, 3–5%/yr sustained, ROI > 10:1.
- SAVE (VMA → AVS → CVS) and EN 12973 are the professional backbone.
Now do it — hands-on assignment
Draft a one-page programme charter: three KPIs you would track, the monthly agenda (30 minutes), and who sits on the value board. If you can't name the people, that's your first action.
Target Costing & Design-to-Cost
You will learn
- Why preventing cost beats removing it — and where target costing came from
- The allowable-cost equation, the value gap, and the cardinal rule
- How targets cascade from vehicle to system to part to supplier
- Design-to-cost at the gates: running cost like weight management
- The handoff to kaizen costing after start of production
13.1 · Prevention beats correction
Everything so far in this course removes cost that already exists. This module is about never letting it in. By the time a concept design is frozen, 70–80% of lifecycle cost is committed while almost none has been spent — so the cheapest VAVE workshop is the one the target made unnecessary. Target costing (Toyota's genka kikaku, developed from the 1960s onward) inverts the traditional logic. Cost-plus asks: what will it cost, and what price does that force? Target costing asks: what will the market pay, and what cost does that allow?
The equation is disarmingly simple: Allowable cost = target market price − required margin. Everything hard about target costing is organisational, not arithmetic: holding the line when engineering says "it can't be done for that", and cascading the number so every team owns a piece of it.
13.2 · Allowable cost, drifting cost, and the value gap
Three numbers run the process. The allowable cost comes from the market, top-down. The drifting cost is the current bottom-up estimate of what the design as drawn would actually cost — it moves with every design decision. The distance between them is the value gap, and closing it is a design activity: function analysis, DFMA, spec challenge, supplier co-design — the entire toolkit of Modules 4–11 pointed forward instead of backward.
Discipline comes from the cardinal rule (Cooper & Slagmulder): the target cost may never be exceeded. If a feature must be added, its cost must be found elsewhere — a different feature trimmed, a design simplified, a make-buy changed. What the rule really bans is the quiet drift where every team adds "just 2%" and the product arrives 15% over. If the gap truly cannot close, the honest moves are to change the product's content or not launch — not to pretend the margin will appear later.
13.3 · The cascade: from vehicle to part to supplier
A single top-level number is a wish. A cascade is a plan. The vehicle-level allowable cost is decomposed to systems (body, powertrain, chassis, electrical…), weighted by function value and benchmark data, then to subsystems and parts, and finally into supplier target prices — shared openly with sourcing partners along with the cost model behind them. Two practices make the cascade survive contact with reality: give each level a small unallocated management reserve (concepts change), and make every target's owner a named engineer, not a department.
13.4 · Design-to-cost: run cost like weight
Aerospace programmes track mass with an owner per subsystem, a live status at every gate, and a recovery plan the moment an allocation is exceeded. Design-to-cost applies exactly that machinery to cost: cost is a specification with the same authority as mass, performance or safety. At each design gate the drifting cost is reported against the target; a gate with a red cost status and no recovery plan does not pass. Practical instruments: trade-off curves (cost vs. performance per concept, so decisions are chosen, not discovered), tolerance–cost curves (tightening a tolerance typically raises machining cost exponentially — challenge every decimal place), and a cost model that updates with the CAD, so engineers see the € consequence of a design choice the week they make it, not at the next quote round.
13.5 · After SOP: the kaizen handoff
Target costing ends at start of production; kaizen costing picks up from there — continuous, incremental reduction against a yearly cost-down target on the running product. The two are one system: target costing decides where the cost curve starts; kaizen costing bends it further down. A mature product organisation runs both, plus periodic VAVE waves (Module 12) when step-change is needed. One warning: kaizen targets applied blindly, year after year, are how quality death-spirals begin — audited function and quality gates apply to cost-downs exactly as they did in the Development Phase (Module 7).
Worked example — cascading an EV traction-motor target
A compact EV must retail at €29,900 with a 22% gross margin → vehicle allowable cost €23,322. Benchmarking allocates 9.8% to the drive unit → €2,286. The motor's share of the drive unit is 46% → €1,052. Current drifting cost: €1,214 — a €162 value gap (13%). The team closes it with a hairpin winding that cuts copper mass 8% (−€38), a housing redesign merging three castings into one (−€61), magnet grade optimisation validated by CAE (−€43), and a supplier gain-share on machining cycle time (−€26). Gap closed: −€168, €6 returned to reserve. Every step is a Module 4–11 technique — aimed before the design froze.

Ratan Tata announced the "1-lakh car" (~US$2,500) in 2003 — the price was public before the design existed, making it the purest large-scale target-costing exercise on record. The team designed to the number: a 624 cc two-cylinder engine, a single windscreen wiper, three lug nuts per wheel instead of four, no radio as standard, and modular construction; suppliers were brought in against open target prices. The Nano launched in 2008 at the promised ₹1 lakh (base variant, ex-factory). Its later commercial struggles are their own lesson — a target cost can be hit while the value proposition ("the cheapest car" as an esteem problem) misses; cost is half of value, never all of it. Toyota, meanwhile, has run genka kikaku on every model since the 1960s — profit is planned at the drawing board, not negotiated afterwards — and it remains the reference implementation the literature is built on.

Common pitfalls
- Setting the target from internal cost history ("last car minus 3%") instead of market-back
- One top-level target with no cascade — nobody owns a number nobody was given
- Breaking the cardinal rule quietly: ten teams each 2% over is a programme 15% over
- Treating the target as sourcing's problem — 70–80% of it is committed by design decisions
- Cost-down targets after SOP with no function/quality gate — the warranty bill arrives two years later
Key takeaways
- Allowable cost = market price − required margin, set before design and cascaded to named owners.
- Value gap = drifting cost − allowable cost; closing it is design work, done with the VE toolkit.
- The cardinal rule: the target is never exceeded — content trades, it doesn't drift.
- Design-to-cost = run cost like aerospace runs mass: owner, gate status, recovery plan.
- Target costing sets where cost starts; kaizen costing bends it down after SOP.
Now do it — hands-on assignment
Take a product you know. Find its realistic street price, subtract the margin the business needs, and cascade the allowable cost over its five biggest systems using your best judgement of their value share. Now compare with what you believe each system actually costs. Where is the biggest value gap — and which module of this course would you point at it first?
