Task Analysis
Breaking down what users need to accomplish into discrete steps, decisions, and information requirements. The foundation for designing interfaces that match how people actually work.
Definition: Breaking down what users need to accomplish into discrete steps, decisions, and information requirements. The foundation for designing interfaces that match how people actually work.
Task analysis deconstructs what users need to do into specific steps, decision points, and information needs. Before you can test whether an interface works, you need to understand the task it is supposed to support.
Why It Comes First
Skipping task analysis means designing for your assumptions about the task rather than the task itself. You end up with interfaces organized by your internal logic instead of the user's workflow.
How to Do It
- Hierarchical Task Analysis (HTA): Break a top-level goal into sub-goals, then into individual actions. Map dependencies—which steps must happen before others
- Cognitive Task Analysis: Focus on the mental work—what decisions are users making, what information do they need, what knowledge are they applying
- Workflow observation: Watch real users perform the task and document what they actually do, including shortcuts and workarounds you did not anticipate
What You Get
A good task analysis gives you a testable model of the user's work. It tells you which steps are error-prone, which require the most cognitive effort, and where your design should reduce friction. It also gives you the tasks for your usability tests—grounded in reality rather than invented scenarios.
