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).
The specific job title is important because it differentiates one position from another. You will want to leave a space at the beginning of your job description template for the position title.
