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.
Specify how the position fits into the organization. Indicate who the job reports to and how the person will function within your organization, helping candidates see the bigger picture and understand how the role impacts the business.
