Run vendor and internal-option due diligence
Review capability, security, privacy, financial health, support, contract, rights and references separately.
Verify independently
- Use official documents, direct demonstrations and references.
- Date each source and finding.
Record conditions
- A conditional pass needs a closure owner and evidence.
- Do not let one strong area erase a failed critical area.
Apply equally
- Internal builds need the same support, security and continuity review.
- Keep sales claims separate from verified behavior.
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.
