What are the main job analysis techinques?

The main job analysis techniques include interviews, questionnaires, observations, and work diaries. Interviews involve direct discussions with employees and supervisors to gather detailed information about job responsibilities and requirements. Questionnaires, often standardized, collect data from a larger sample to identify common tasks and competencies. Observations allow analysts to see the job in action, while work diaries enable employees to record their activities over time for a comprehensive understanding of job demands.
