ABSTRACT
Observation is often used in task analysis to collect data about how tasks are normally performed in actual settings. When task analysts want to know what tasks are done by workers in a particular job, they observe some workers and record the tasks they see them completing. Observation has long been a primary way to collect data for task analysis. Michalak and Yager (1979) indicated that direct observation of tasks being performed was the most valid method of collecting task analysis data. They stated that in many cases direct observation is also the most desirable data collection method.
