Pugh Concept Selector

Q: What is a Pugh concept selector?

A Pugh selector is a weighted decision matrix that helps teams compare multiple concepts against the same engineering criteria.

Q: When should you use a concept selection matrix?

Use a concept selection matrix when several directions remain plausible and the team needs a transparent rationale for narrowing options.

Compare three concept directions against the same weighted engineering criteria. This keeps early-stage decisions explicit instead of burying them in meeting notes and opinions.

Inputs

Concept A name

Concept B name

Concept C name

Criterion	Weight	Concept A	Concept B	Concept C
Customer value
Technical feasibility
Manufacturability
Sustainability
Commercial attractiveness

Scores are intentionally simple. Use the matrix to structure debate, then challenge any criterion where the weighting itself looks wrong.

Results

Why this tool matters

Teams often jump between feasibility, user need, cost, and sustainability without a common structure. A weighted matrix forces the discussion into the open so trade-offs are visible and contestable.

If one concept scores well on value but weakly on manufacturability, the right response may be to derisk the concept rather than discard it. The matrix should guide questions, not shut them down.

Use it well

Keep criteria stable across all concepts.
Weight only the factors that actually matter to the decision.
Use the result to identify the next de-risking step, not just a winner.

FAQ

What is a Pugh concept selector?

A structured comparison matrix that scores concepts against the same criteria so teams can make design trade-offs transparently.

When should you use a concept selection matrix?

Use it when several options remain plausible and the project needs a shared rationale for prioritising which concept to carry forward.

How this calculator works

Early-stage estimate, not final quotation

This calculator turns the assumptions you enter into an early engineering or commercial estimate. It is most useful for comparing options, surfacing trade-offs, and deciding what needs deeper validation next.
