A job description is an internal document that clearly states the essential job requirements, job duties, responsibilities, and skills required to perform a specific role. A more detailed job description will cover how success is measured in the role so it can be used during performance evaluations. They are also known as a job specification, JD, and position description (job PD).
You may find it useful to leave a section on your template to be used for detailing the supervision of a particular position, and/or the extent to which it is supervised. This can help an individual understand who he or she would report to while performing a particular position, and the role of the position within the hierarchy of a company or organization.
