You may find it useful to leave a section on your template to be used for detailing the supervision of a particular position, and/or the extent to which it is supervised. This can help an individual understand who he or she would report to while performing a particular position, and the role of the position within the hierarchy of a company or organization.
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.
