Step-by-step explanation:
Four popular methods of job analysis include the Position Analysis Questionnaire system, the Critical Incident Method, the Task Inventory Analysis, and the Competency-Based Analysis. The Position Analysis Questionnaire system is a structured instrument used to quantify job behaviors and requirements.
The Critical Incident Method involves identifying and describing specific incidents where exceptional behavior led to particularly successful or unsuccessful outcomes, providing insight into important job functions. The Task Inventory Analysis entails creating an exhaustive list of job tasks, often with ratings regarding their frequency and importance.
Lastly, Competency-Based Analysis focuses on the personal attributes or competencies such as knowledge, skills, and abilities required to perform the job successfully.
