What is a job analysis?

Job analysis is a systematic process that involves identifying and documenting the essential tasks, responsibilities, and behaviors required for a job. It also assesses the qualifications, skills, and knowledge needed to perform those tasks effectively. The outcome of a job analysis includes detailed job descriptions and specifications, which are used for various HR functions such as recruitment, selection, training, performance appraisal, and compensation.
