How do we make product comparisons actually fair?

Force all suppliers to quote against the same operating-point, interface, and compliance assumptions before price comparison.

What is the most common reason for re-quote loops?

Unfrozen interface and duty-cycle inputs. If those change late, architecture and cost assumptions usually change as well.

Start with a narrow candidate set, then use sample evidence to converge. This reduces both delay and decision noise.

Project Stage	Evidence to Check	Buyer Output
Model shortlisting	Torque-speed envelope, thermal duty, packaging limits	2-3 viable model candidates
RFQ refinement	Interface revision lock, quantity profile, compliance scope	Comparable quote set with fewer caveats
Sample gate	Test matrix tied to real operating scenario	Architecture confirmation or pivot decision
