Task analysis is used to develop a thorough understanding of a process and its underlying tasks. Task analysis employs a wide range of methods such as interviews, on-site observation, or diary studies. It looks into what people are doing, what they are trying to achieve, and in what way they are going about it. Observed processes are broken down in tasks and subtasks, compiled in a task report. The information gleaned from task analysis establishes a foundation of existing practices and is used to define the requirements and the technical architecture of a new system.
