Task analysis

• Synonyms - task decomposition

Task analysis is another data capture technique. It is used to break tasks into simpler, more readily understandable subtasks.

For example, getting a train ticket on a website for later collection might be broken down into ordering, paying and collection (which would in turn be broken down into other simpler sub-tasks).

The aim of task analysis is better understanding of how a user performs a given task. In other words, task decomposition should generate a clear picture of what a user is doing (or is required to do) in terms of actions and/or cognitive processes to achieve some given end (i.e. acquiring a train ticket).
