Job analysis is a systematic process of collecting and analyzing data related to the duties, responsibilities, and requirements of a specific job role. It involves gathering information about the knowledge, skills, abilities, and other characteristics required to perform the job successfully. This information is then used to develop job descriptions, determine job classification, design compensation systems, and identify training and development needs. Job analysis requires specialized skills in data collection, analysis, and interpretation, as well as knowledge of legal and regulatory requirements related to employment practices.
