How should we decide when proposals remain close?

First eliminate unresolved critical gaps: unsupported technical treatment, unidentified delivery lead, hidden external cost or unacceptable data terms. Then score the remaining candidates using the separate scorecard, run a downside cost case and compare contract clarity.

If the choice turns on one unresolved specialist issue, purchase that review rather than signing a broad annual engagement under uncertainty. Preserve the option to stay with the incumbent if the evidence supports it.
