Change one variable at a time and preserve a known-good project state.
Start with a clear goal
Before changing a project, describe the intended result in plain language. Identify what the user should see, what the system should do, and which parts of the experience are in scope. A narrow goal makes it easier to test whether the implementation actually works.
Prepare a safe working copy
Duplicate the project or create a separate test place. Keep original files unchanged, record where every external asset came from, and avoid running unfamiliar code in a production experience.
Work through the details
- Inspect the structure. Review names, hierarchy, dependencies, and client/server boundaries.
- Check assumptions. Confirm file types, API usage, scale, resolution, permissions, and setup steps.
- Implement incrementally. Add one component at a time and keep changes easy to isolate.
- Test realistic conditions. Include repeated actions, missing data, different device sizes, and unexpected inputs.
- Write down limitations. Record what was tested, what remains unknown, and how to reproduce the result.
Common mistakes to avoid
- Assuming an imported model contains only geometry.
- Copying code without understanding dependencies or trust boundaries.
- Leaving license and attribution checks until after publication.
- Testing only the happy path on one device.
- Using “safe,” “optimized,” or “compatible” without evidence.
Review checklist
Before you consider the work ready:
- The intended behavior is documented.
- Every external file has a known source and permission status.
- Scripts and dependencies have been reviewed.
- Important edge cases have been tested.
- Known limitations are visible to the next person.
