Handoff Lessons

When a Correct Revision Never Arrives

A revision can be technically correct and still fail. It passes review, it is approved, and then it disappears between review and implementation. The change exists in the model but not in the issued drawings, or in the drawings but not in the subcontractor's scope. This collection gathers case files where the lesson was not about the decision itself but about how the decision was handed off.

Where Handoffs Break

The files identify the common break points. The review team approves a change but does not record who must action it. The model is updated but the transmittal is not. A late requirement change arrives after the handoff package is closed, and no one reopens it. Each case lists the handoff summary, what was transmitted, to whom, and what was assumed but never confirmed.

Lessons to Reuse

These cases are written to be reused. Each one ends with a lessons-learned section that distills the failure into a single checkable rule: confirm the action owner, confirm the transmittal, confirm the package was reopened for late changes. Pair this collection with the decision-timelines files to see exactly where in the sequence the handoff was lost, and use both to tighten your own review-to-implementation path.
