the collection and analysis of information about a specific job. Data are obtained through interviews with or written questionnaires from those doing or supervising the job, or through observation or audiovisual recordings of the job in action. Important classes of information include the behaviors, tools, working conditions, and skills involved in the job. Job analysis is the first step in developing effective personnel selection, employee evaluation, job evaluation, and personnel training programs. Once data have been collected, the role of the job analyst is to use statistical techniques and subjective judgment to determine the primary dimensions of a job and to identify those positions that are sufficiently similar to be classified as the same job.
