Job analysis is a systematic process of collecting information about job tasks, duties, responsibilities, and requirements. The outcomes are a job description, which outlines the tasks and responsibilities, and a job specification, which lists the necessary qualifications. Strategic choices in job analysis include the level of employee involvement, the level of detail collected, how often analysis is conducted, whether the focus is past or future job requirements, and the sources of job data. Job analysis data is used for human resource planning, recruitment and selection, training and development, job evaluation, performance management, and health and safety purposes. Common methods for collecting job data include observation, interviews, questionnaires, checklists, and diary records from employees.
