Common Problems
Design looks great but implementation looks like a cheap knockoff. Missing edge cases and states. Endless revision cycles. Disorganized deliverables.
Efficient Workflow
Kickoff meeting before design starts. Low-fi prototype review with devs before final design. Formal design review meeting. Designer participates in UI acceptance testing.
Deliverable Standards
Source files (Figma/Sketch), design spec doc, slice assets, interaction notes, empty/error/loading states.
