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.
Of course, the job description should specify education, previous job experience, certifications and technical skills required for the role. You may also include soft skills, like communication and problem solving, as well as personality traits that you envision for a successful hire. While you may be tempted to list out every requirement you envision for your ideal hire, including too many qualifications and skills could dissuade potential candidates.
