Most important, I stayed involved when the design became code. Before I started design QA, I scheduled time with the developer and product owner to explain how I wanted to work through the review and make sure we agreed on the process.
That relationship mattered. Design QA can feel like someone arriving late to point out everything engineering did wrong. I wanted the developer to know that I cared about the shared result, that I had documented the design carefully, and that I would work through discrepancies with him rather than throw a screenshot of red circles over the wal
The implementation arrived in three major segments: the modal, edit mode and view mode. For each segment my design QA had four review steps:
1. Interaction behavior — verify every annotated requirement from Figma worked as written.
2. Visual and responsive accuracy — compare the implementation against the intended UI and at the sizes I had designed.
3. Design-system implementation — inspect the rendered code and verify that the appropriate design-system variables were actually being used.
4. Dark mode — confirm that the alternate theme behaved and looked like the design rather than treating it as an afterthought.
I created Excel sheets where I logged the bugs I found with screenshots and detailed reproduction information. Across the review process I logged more than 20 implementation issues that the developer then fixed.
