Strategy & Vision
UI improvement is a discipline, not an event. Products that maintain quality over time treat the interface as a living system requiring continuous observation, structured evaluation, and targeted intervention based on real evidence.
Execution & Design
Heuristic evaluation provides the starting point: systematic expert review against usability principles that identifies friction patterns without user testing. Experienced practitioners surface a significant proportion of real problems quickly.
Impact & Growth
User testing validates heuristic findings — revealing the gap between what designers intended and what users actually experience. This gap is almost always larger than teams expect, making testing against real behaviour non-negotiable.
Conclusion
Prioritisation is where most improvement initiatives fail.
