As a follow-up to Chap. 5, this chapter discusses the important work analysis technique of task analysis. Task analysis is the process of identifying the component behaviors within a task. A task is defined as a unit of work with a defined beginning and ending, discrete from other tasks, and has an outcome at the end. The chapter identifies six patterns of task behavior: procedure, troubleshooting, decision making, inspection, adjustment-revision, and manage a work process. These patterns tend to appear with some regularity across most jobs. The chapter presents a process for conducting a task analysis. For many human resource development professionals, task analysis may be one of the most important sets of skills related to work analysis.
