incremental-implementation

Manage large code changes by breaking them into small, testable slices. This approach implements one piece, tests it, verifies it, and commits before moving to the next, keeping the system releasable.

The best way to refactor incrementally is using vertical slicing. Build one complete path through the stack, validate it, and then expand to ensure each increment leaves the system in a working state.

Start implementing a feature by breaking the task into small slices. Implement the smallest piece, test it, verify it, commit, and then proceed to the next slice to maintain steady progress.

Use risk-first slicing during software development when tackling the riskiest piece of a feature first. This strategy mitigates uncertainty early in the incremental cycle before expanding to stable slices.

Contract-first slicing works for multi-file feature changes by defining the API contract first. You then implement the backend against the contract to keep changes small and testable.

Writing a large amount of code at once feels difficult because it lacks frequent validation. Delivering changes incrementally enforces an implement-test-verify-commit cycle, making large features manageable.
