GOMS / KLM Analysis

Use this skill when the useful artifact is an explicit workflow model. It is best for repeatable tasks with known steps, such as dashboard triage, form submission, search/refine/open flows, command palettes, editor workflows, and mobile settings tasks.

Choose The Model

• Use KLM when the task is procedural and the user already knows what to do. It estimates expert, error-free execution time.
• Use GOMS when there are meaningful alternatives, decision rules, or multiple methods to achieve the same goal.
• Use a lightweight cognitive walkthrough when the risk is discoverability, comprehension, or first-time use rather than speed.
