How it works

Keep this in mind.Contract Necessity works one way for a lean team and another for a large one. The mechanics follow the context.

The working rule is plain. Agree what Contract Necessity covers first, then act on it. Skip that order and Contract Necessity loses its shared meaning, and two teams end up measuring two different things. Read that twice.
