Think of this as describing the purpose of the position, and its role within your company or organization as a whole. A job summary will briefly acknowledge the fundamentals of the position, so leave space on your job description template to answer.
Job functions should be qualified whenever possible and the desired outcome of the work should be described, rather than the method for accomplishing that outcome. For example, instead of saying, “she files folders” write that “the clerk files folders alphabetically based on category." Employers should let individuals read their job descriptions, voice any concerns, and sign their descriptions. Job descriptions should be accurate. To ensure accuracy, combine the input of many managers and employees.
