Turn a vague project scope into typed phases - what goes in, what comes out, what "done" looks like, who signs off and by when, what triggers payment, and what is explicitly excluded. Use when scoping freelance or contract work, breaking a project into milestones, writing a statement of work, defining acceptance criteria, or when a project has no written definition of done. Flags every field the client has not given you enough information to fill, instead of inventing it.
