It passed tech review. But the field couldn’t install it—and the PM had to answer for it.
Spec deviations aren’t inherently risky. What’s risky is when they aren’t communicated clearly—or don’t include the field-side impact. By the time QA flags the delta or a crew pauses mid-install, it’s already a black mark.
Common deviation misses:
Product approved “as equal,” but changes rigging or anchor layout
Cure profile differs—and QA wasn’t informed
Drawings reissued—but site team still working off old version
What PMs remember:
“They told procurement it was fine—but the field had no clue.”
“We wasted six hours sorting out what was approved vs. what got shipped.”
“We had to pause work while they chased down updated documentation.”
Distributors who avoid postmortem blame:
Provide install deltas in plain language—not just spec charts
Pre-validate field compatibility and notify supers of every change
Send updated submittals, install sheets, and QA notes bundled with shipment
Deviations don’t kill jobs. Silence around deviations does.
