What Decision Matrix does
Compare alternatives against weighted criteria, inspect evidence and record the decision separately from the score.
A decision matrix helps a team apply the same questions to every alternative. Agree what matters before scoring, and make the meaning of a high score clear.
In InnovationFlow, scored options and recorded decisions remain separate. You can explain why an option was selected, deferred or rejected instead of treating a rank as automatic approval.
ASQ describes decision matrices as a way to compare options against criteria. InnovationFlow adds explicit decision status, rationale and ownership to the assessment.[1]
Illustrative scores within the 0 to 10 scale, with higher always better. The risk criterion means lower exposure earns a higher score. Weights are examples, not recommended defaults.
| Option | Strategic fit 30% | Capability 25% | Speed 20% | Risk 25% | Weighted result |
|---|---|---|---|---|---|
| Retrofit | 4 | 5 | 2 | 3 | 3.60 |
| Modular redesign | 3 | 2 | 5 | 4 | 3.40 |
| New platform | 5 | 4 | 4 | 3 | 4.05 |
| Defer investment | 2 | 3 | 3 | 5 | 3.20 |
Re-test the ranking when a weight or uncertain score changes.

Understand the method
The parts in plain language
Criterion
A distinct basis for comparison with a consistent scoring direction.
Illustrative example
A high serviceability score means easier maintenance.
Coverage
Missing scores represent unfinished assessment.
Illustrative example
No supplier test result means unassessed, not zero performance.
Decision rationale
Explain the judgement behind the final choice.
Illustrative example
Defer the highest-scoring route until its seal-life test is complete.
When to use it
- When several options need a consistent comparison.
- Before selecting an initiative for a roadmap.
A practical workflow
- 1
Define comparable options and agree criteria and weights.
- 2
Score each criterion from 0 to 10 using stated evidence; leave unassessed criteria blank.
- 3
Inspect coverage, ties and the effect of the criteria on the result.
- 4
Record selected, not selected or deferred status, with a decision owner and rationale.
Fictional worked example
Choosing a pump development route
This example is illustrative rather than a reported case. A fictional engineering team compares retrofit and redesign options.
Observation:Serviceability and energy use matter for the target segment.
Implication:Agree weights with the people making the decision.
Observation:The new seal material has not completed endurance testing.
Implication:Leave the assessment incomplete and commission a test.
Observation:Proceed with the retrofit pilot.
Implication:Record why the pilot is appropriate now.
From analysis to decision
How to interpret the result
- 1Use the result to structure discussion, including disagreements.
- 2Revisit the decision when evidence or priorities change.

What a useful output looks like
Common pitfalls
- A high total does not override a mandatory safety or eligibility requirement.
- Do not disguise missing evidence as zero or count the same benefit in several criteria.
