1. Purpose of the gate
This gate fixes the frame for the whole program. Once it passes, the gap assessment measures against this scope, the process office builds to it, and the formal assessment is planned on it. A scope that is wrong here is the most expensive mistake in the lifecycle, because every later stage inherits it.
The reviewers check that the scope comes from the customer's actual requirements and the organisation's actual work, that the target levels are plausible for the time available, and that the model version and plug-ins match what the customer will assess. Several of the lifecycle's founding decisions are frozen here.
