Function–Cost Matrix & Value Index

Load every unit of cost onto the functions it serves. VI = Cost ÷ Worth. Anything above 2.0 is a creative-phase target.

Baseline cost

Step 1 · Allocate component cost to functions

List components down, functions across. Split each component's cost across the functions it serves (% or absolute). Columns must sum to the function's total cost; rows must sum to the component's cost.

Component ↓ / Function →	F1	F2	F3	F4	F5	F6	Component €










Function cost total

Step 2 · Score value mismatches

Function (verb–noun)	Type	Cost €	Worth €*	VI = C÷W	Verdict / first idea directions

*Worth = the lowest cost that could still reliably perform the function — estimate via the cheapest known way anywhere (any industry) to achieve it. Verdicts: VI ≤ 1.2 healthy · 1.2–2.0 watch · > 2.0 attack.
