Using direct observation, a person conducting the analysis simply observes employees in the performance of their duties, recording observations as they are made. The observer either takes general notes or works from a form which has structured categories for comment. Everything is observed: what the worker accomplishes, what equipment is used, what the work environment is like, and any other factors relevant to the job.
Direct observation methods have certain natural limitations for job analysis purposes. First, they cannot capture the mental aspects of jobs, such as decision making or planning, since mental processes are not observable. Second, observation methods can provide little information relating to personal requirements for various jobs because this kind of information is also not readily observable. Thus, observation methods provide little information on which to base job specifications.
