Step-by-step explanation:
A job analysis determines information about a job - the tasks that comprise it and then the environment in which it will be performed. Job analysis is a process used in industrial psychology, which is a branch of I-O psychology. It involves accurately describing the tasks or job and identifying the characteristics required of the worker to successfully perform the job.
Observation, surveys, and interviews are used to obtain the information required for job analysis. These methods help gather information from proficient individuals and gather consensus on the job requirements.
According to Davis and Moore, the degree of skill required for a job determines its importance. Jobs that require more skill have fewer qualified people to do them.
On the other hand, jobs with lower skill requirements have more qualified applicants. Job analysis helps organizations understand the skill requirements and characteristics needed for different roles
