The best way to create and manage consistent, concise and effective job descriptions is to start with best-practice job description templates. A well designed template ensures employees, managers, HR and the organization overall get all the information they need, while making the associated tasks easier for everyone.
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.
Prepare job summaries, if relevant. You can use the job description template you use for each position that you advertise by filling in the template with the information that is relevant to that position. However, if you do (or expect to do) a lot of hiring of a particular position, you might make a special template that includes a summary of that job. This will save you some time.
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.
