Compare vendors and delivery options without losing the facts
Keep weighted criteria, mandatory failures, evidence and operating costs distinct.
Normalize the response
- Map every response to the same criteria and identify missing evidence.
- Do not reward a polished response for avoiding a hard requirement.
Inspect the whole lifecycle
- Compare implementation, operation, support, change, recovery and exit—not only the initial feature list.
- Include internal review and migration effort in the decision record.
Record why
- Retain the evidence and reasoning behind the selection.
- Revisit the decision when assumptions, prices, dependencies or requirements change.
Keep the result reusable
The engagement studio carries the same workflow identity into six reviewable artifacts. It does not send a request, select a vendor, create a contract or approve a purchase.
