The operating problem

The decision is one moment. Its basis is scattered across the set.

A requirement can sit in a specification, a conflicting quantity on a drawing, and a missing responsibility in a trade scope. The review has to connect them before the commitment is made.

Drawing to specification: An indicated assembly and its written requirement can carry different assumptions.
Contract to trade scope: Ownership, exclusions, and handoffs can depend on language outside the scope sheet.
Revision to decision: A later issue can change the basis the project team believed it had reviewed.

Discovery standard
