What is the importance of job description?

A job description is a list of the duties that the jobholder is expected to perform. Some other items that are included in a job description are level and type of education required, experience required, physical exertion required (such as how many pounds a person would be expected to lift, how far a person would have to walk) other skills required (such as needing to have a clear speaking voice, be bilingual in English and Spanish, or know the safety regulations of a certain state government.)
