incremental-implementation

You can break large multi-file features into safe incremental slices by implementing one thin vertical slice at a time, testing and verifying each step before moving on to keep changes rollback-friendly.

The best way to ship multi-file features without risky merges is to deliver them in incremental slices, maintaining test-and-verify discipline after each step to catch issues early and keep the project compilable.

Incremental implementation keeps code review manageable by limiting each commit to a focused, working increment, ensuring the changes are small, testable, and easier to review than one massive merge.

Yes, you can use incremental slices for both new features and code refactoring, as the approach applies to any changes too large to ship in a single pass by keeping scope controlled and rollback-friendly.

You should avoid shipping a large change in a single pass when it spans multi-file features or refactors, as doing so risks becoming untestable and hard to review without slice-by-slice verification.
