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.
What are some tips on how to write a professional job description? Make sure the title of the job position and description match. Do your research. If you are not familiar with the job, talk to someone who is and have them help with the description. Make sure it clearly defines the goals of the position and a timeline for reaching them.
