Task Analysis -The result of a task analysis is a description of the tasks that users undertake when interacting with the system. -It also involves considering how individuals carry out these task. -The typical use of a task analysis is to describe an existing system or task before serious design work starts on a new system to replace it - The aim of task analysis is to find out what the old system enables users to do, so that the designers can understand what is required of the new system. -A description of existing user tasks enables the designers to review those tasks- and hence to redesign, re-implement or remove them from the new system. Note: the analysis should inform, but not constrain, the development of the new system. Following a development method is not a substitute for innovation -Provides a means of analyzing and describing the jobs and task that people do so that they can be supported by interactive computer systems. -Provides both method of analysis and notation to capture the results. -The focus is on people’s goals and the actions they carry out to achieve those goals.Purposes of task analysis -to help designers to understand existing systems
