Plan and run moderated usability tests, then turn findings into prioritized fixes, grounding design decisions in evidence.
Conduct heuristic evaluations and benchmarking to catch problems early, while they're less costly to fix.
Run and analyze card sorts to structure navigation around how people actually think, so users can find what they need without guessing.
Design and interpret A/B and multivariate tests to prove which version performs.
Build conversion funnels and run root cause analysis to pinpoint where users drop off and why.
Quantify interaction efficiency with Fitts' Law and the Keystroke-Level Model to make frequent tasks measurably faster.
Audit interfaces against WCAG accessibility standards and optimize for search (SEO) to widen reach and reduce legal exposure.
Design usable forms, navigation, and visual layout using layout grids, visual hierarchy, and Gestalt grouping.
Apply persuasion and trust techniques, from credibility cues to emotional journey mapping, to build the trust that lifts conversion.
Build personas that keep real users at the center of every decision, as well as the requirements and prototypes that turn insight into tested design.
Integrate UX into Agile delivery using the Parallel Streams approach and design maps, keeping design and research one cycle ahead of development.
Use the psychology of attention and perception to guide the eye to the most important elements first.
Apply human error theory to design interfaces that help users avoid mistakes and recover from them.
Distinguish conceptual and domain models and use them to provide a shared understanding across a team.
Use the inverted pyramid and readability metrics so users can find and act on content quickly.
Design dynamic interfaces with AJAX that update smoothly without disorienting users or compromising SEO and accessibility.
Close the empathy gap with empathetic design techniques, replacing vague user stories with persona stories that keep development grounded in real user needs.
