A job description may include relationships with other people in the organization: Supervisory level, managerial requirements, and relationships with other colleagues. A job description need not be limited to explaining the current situation, or work that is currently expected; it may also set out goals for what might be achieved in the future, such as possible promotion routes and conditions.
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.
