According to Torrington, a job description is usually developed by conducting a job analysis, which includes examining the tasks and sequences of tasks necessary to perform the job. The analysis considers the areas of knowledge and skills needed for the job. A job usually includes several roles. According to Hall, the job description might be broadened to form a person specification or may be known as "terms of reference". The person/job specification can be presented as a stand-alone document, but in practice it is usually included within the job description. A job description is often used by employers in the recruitment process.
A bank of job descriptions can be instrumental in supporting the development of other organizational documents and standards as well. Descriptions may offer a framework for developing performance evaluations. In addition, the information gleaned may provide a common thread for developing employee resumes, policy manuals, annual reports, and organizational media.
