This article keeps that concern within an industrial engineering and procurement context. Begin by defining the governing context.

Use project drawings, nameplates, manufacturer instructions and the governing standard together; no single catalogue value describes the whole duty. Where information conflicts, stop and resolve the discrepancy before changing settings, conductors or equipment. A disciplined review separates verified facts from assumptions. Mark each input as measured, calculated, specified or still unknown. Then identify the acceptance criterion and who has authority to approve it.
