Implementation planning transforms designs into granular tasks by scoping post-design work, defining architecture notes and tech stack, estimating task effort, and writing concrete steps with exact file paths, test commands, and environment details. This enables precise handoffs and reproducible execution.

A complete implementation plan contains a header, architecture notes, tech stack specification, estimated tasks with granular steps, exact file paths for changes, test integration points, commit markers, concrete commands to run, and environment requirements—everything needed for reproducible execution without additional context.

Break features into bite-sized tasks by defining each task's scope, listing specific steps with file paths and commands, integrating tests at each step, marking commit boundaries, and specifying environment setup. This granularity ensures developers can execute each task independently and verify progress.

Yes. Detailed implementation plans with exact file paths, concrete commands, test integration, and environment requirements guide developers who lack context, reducing onboarding time and enabling reproducible execution without requiring design knowledge or prior codebase familiarity.

A design outlines what to build and why; an implementation plan specifies how to build it. Plans add post-design, pre-code detail: estimated tasks, granular steps with exact file paths, concrete commands, test requirements, commits, and environment setup—the actionable bridge between design and execution.
