SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

UX teams often spend excessive time surfacing and prioritizing design issues across interfaces. This skill provides an evidence-backed evaluation against a comprehensive 168-principle taxonomy to identify concrete UX flaws with citations that support business impact.

Core Features & Use Cases

  • Applies a comprehensive 168-principle taxonomy covering cognition, core heuristics, design systems, interface patterns, specialized domains, and accessibility to surface actionable issues.
  • Requires every finding to cite the principle code and quantify potential business impact, enabling rigorous design reviews and pre-launch checks.
  • Use Case: run a design audit on a new screen and generate severity-graded findings to guide iterative improvements before rollout.

Quick Start

Provide a UI design or mockups for evaluation and receive a structured audit report with cited principles and severity levels.

FAQPage Schema
How do I conduct a UX design audit before a product launch?

To conduct a UX design audit, provide your UI mockups for evaluation to generate a structured report with severity-graded findings and cited principles. This surfaces concrete flaws to guide iterative improvements before rollout.

What is a 168-principle taxonomy in UX/UI evaluation?

A 168-principle taxonomy in UX/UI evaluation is a comprehensive framework covering cognition, core heuristics, design systems, interface patterns, specialized domains, and accessibility. It surfaces actionable interface issues with evidence-backed citations.

How do I quantify the business impact of usability and accessibility issues?

You quantify the business impact of usability and accessibility issues by applying an evaluation framework that requires every finding to cite a principle code and a quantified business impact. This ensures recommendations are actionable.

Can I use heuristic evaluation for both design systems and interface patterns?

Yes, you can use heuristic evaluation for both design systems and interface patterns. The evaluation applies a comprehensive taxonomy across these domains, along with cognition and accessibility, to surface cited design issues.

What is the best way to prioritize UI design issues found during a review?

The best way to prioritize UI design issues is to evaluate interfaces against a principle taxonomy that generates severity-graded findings. Every issue includes a principle code citation and a quantified business impact to guide actionable prioritization.

When should I not use a comprehensive taxonomy for a design review?

You should avoid using a comprehensive 168-principle taxonomy for a design review if you lack UI mockups to evaluate or need a quick, informal check rather than a rigorous, evidence-backed audit with quantified business impact.
