Phase 0: Definition & scoping

Yes. If the brief is already clear enough, you can go directly into a Defined-scope sprint.

The key question is whether the work can be scoped and delivered without major unknowns, hidden assumptions or unresolved decisions that are likely to cause delay or abortive work later.

Where only a few points remain open, these can often be resolved through the initial discussion and proposal process. Phase 0: Definition & Scoping is more appropriate where the problem is still open-ended, disputed or insufficiently defined to establish a reliable delivery scope.

A quote prices a defined piece of work against a sufficiently clear brief. Phase 0: Definition & Scoping helps establish that brief where important matters still need to be worked through first.

Depending on the problem, that may involve clarifying the objective, requirements and constraints; organising incomplete information; making assumptions and unknowns explicit; identifying risks or dependencies; and comparing possible routes forward.

The result is a clearer basis for deciding what should happen next and for scoping any subsequent engineering work with greater confidence. That next stage can be commissioned from me or used to brief another suitable provider.

Where the initial brief is already clear enough to price and deliver responsibly, I will propose the defined work directly rather than recommend Phase 0 unnecessarily.
