plan-feature

To turn a vague feature request into an implementation plan, you must clarify scope, investigate the current state, and define testable acceptance criteria. This process creates a structured, implementation-ready plan that surfaces unknowns and dependencies before coding begins.

Feasibility analysis for non-trivial feature design involves investigating the codebase and current state to identify risks and dependencies early. It produces a structured evaluation that determines whether a proposed feature is technically viable before development starts.

Writing Given/When/Then acceptance criteria for pre-code feature planning requires clarifying requirements and defining testable conditions for each scenario. This formats the expected behavior into explicit, verifiable statements that developers can use to validate the final implementation.

Yes, defining product delivery phases is required before getting approval for implementation. Structuring the work into an ordered implementation plan with clear dependencies ensures stakeholders review a complete, feasible roadmap and explicitly approve it before coding begins.

Yes, you can use this feature planning approach for redesigning existing functionality. It applies to both new feature design and redesign scenarios by investigating the current state, clarifying unknowns, and producing a structured implementation plan for the updated scope.

If technical investigation reveals unknown risks during feature planning, you should document them in a feasibility table and clarify the scope. This early visibility allows the team to adjust the implementation plan and acceptance criteria before requesting approval.
