Employers should develop job descriptions that clearly define the essential functions of every job before advertising the job or interviewing applicants. A job description should have clear, concise, non-technical language, and avoid unnecessary words. The job description should focus on words that have a single meaning with detailed explanations for words that may be interpreted differently. Each sentence should begin with an active verb and use the present tense. Examples of job functions should be provided. The desired outcome of the work should be described, rather than one method for accomplishing that outcome. For example, instead of "writes down notes during meetings" put "records notes during weekly meetings." Writers should avoid using gender-specific language, jargon, technical language, proprietary names (Xerox), and ambiguity.
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).
