Explanation:

Job analysis refers to the process of collecting information about a job. In other words, it refers to the anatomy of the job. Job analysis is performed upon ongoing jobs only. It contains job contents. For example, what are the duties of a supervisor, grade II, what minimal knowledge, skills and abilities are necessary to be able to adequately perform this job? How do the requirements for a supervisor, grade II, compare with those for a supervisor, grade I? These are the questions that job analysis answers.

According to Jones and Decothis “Job analysis is the process of getting information about jobs: specially, what the worker does; how he gets it done; why he does it; skill, education and training required; relationship to other jobs, physical demands; environmental conditions”.
