Job analysis is a systematic process of collecting information about the tasks, duties, responsibilities, and requirements of a job. It involves determining the purpose, processes, and types of information collected through methods like observation, interviews, questionnaires, and expert panels. The outcomes of job analysis are used to create job descriptions, specifications, and evaluations. Job descriptions outline the duties and responsibilities of a role, specifications list the minimum qualifications, and evaluations determine the relative value and compensation of jobs. Questionnaires are a common and cost-effective method used to collect job analysis data, especially from large numbers of employees.
