Feature Scope

Defining session boundaries keeps feature scope controlled by explicitly listing allowed activities like adding features and writing tests, while flagging disallowed actions such as removing functionality or changing public APIs without approval.

Session boundaries in feature planning are defined limits that separate allowed activities like extending APIs from disallowed actions like changing public APIs without approval. They ensure stability, documentation, and error handling quality requirements are upheld during development.

To maintain stability when adding features, enforce quality requirements that keep existing tests passing and handle errors gracefully. Adequate test coverage and proper documentation must be verified before finalizing any scope-controlled task.

The best way to verify feature changes stay within defined boundaries is using a verification checklist. This confirms each feature meets requirements, tests and coverage exist, error cases are covered, and work stays in scope before finalizing the task.

Changing public APIs is flagged as a disallowed action within feature scope boundaries unless explicit approval is granted. Scope control ensures stability by preventing unauthorized modifications to existing functionality during incremental delivery.

You need to define session boundaries before starting every new feature session within ongoing projects. This prevents unchecked feature work from destabilizing systems and delaying delivery by keeping new functionality focused and safe.
