Successful completion is only one state in a business workflow
Partial fulfillment creates a different cancellation problem from canceling an untouched order. Some goods or services may already have been delivered, so the project needs to know which remaining actions can stop and what history must remain visible. The checklist should expose that state transition without prescribing refunds, returns, or accounting behavior that the sources do not mention. The reviewer can decide that the scenario belongs elsewhere, is excluded from this release, or requires additional requirements. Each outcome is more informative than a generic missing-feature warning. A useful walkthrough begins with a partially completed order and asks the owner to identify the next permitted steps from the available documents. Record where the explanation stops. That stopping point is evidence of an unresolved scope question, not proof that a particular cancellation feature must be built.
Working through the example
An order project describes creation, approval, and fulfillment but says nothing about cancellation after partial fulfillment. The checklist exposes this unaddressed transition. Ask whether partial cancellation is in scope, then record the answer and any resulting requirement. Keep a justified out-of-scope answer visible instead of inventing behavior.
A discriminating check
Walk an example order through partial fulfillment and a cancellation request. A generic lifecycle checklist can overreach; the organization must confirm that this transition occurs in its actual work. The completeness study motivates questions against a scoped domain model. Its modeled omissions do not establish that every flagged gap deserves a new requirement in this project.
