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).
A job description may include relationships with other people in the organization: Supervisory level, managerial requirements, and relationships with other colleagues. A job description need not be limited to explaining the current situation, or work that is currently expected; it may also set out goals for what might be achieved in the future, such as possible promotion routes and conditions.
