ITP (Inspection and Test Plan)
The document setting out what will be inspected, when, by whom, against what criteria, and with what hold and witness points. It is agreed before the work starts — which is the only time it can be agreed honestly.
An ITP written after the work has begun is a negotiation dressed as a plan. Written beforehand, when nobody yet has a reason to prefer a particular answer, it is a genuine control — and it removes the argument about whether an inspection was required at all.
The heart of it is the hold and witness points: the moments at which work stops, or at which the client has the right to attend. Get those wrong and you have either a bottleneck nobody can meet or a set of inspections that never actually happen.
