Build a weighted requirements and evidence matrix
Connect must, should and could requirements to evidence without letting scores obscure critical failures.
Weight visibly
- Weights must total 100 and remain reviewable.
- Criticality and weight answer different questions.
Require proof
- Specify what evidence satisfies each requirement.
- Use demonstrations and retained artifacts where possible.
Respect musts
- A weighted total does not override a failed must requirement.
- Record accepted exceptions explicitly.
Keep selection explicit
The Sourcing Decision Studio retains the complete evidence chain. Scores, shortlist state and diligence do not select an option without a retained owner decision.
