A job description is a critically important document used for hiring and managing employees. It communicates the responsibilities of the person doing the job, and the qualifications and skills that are needed to complete it. Having a template for all job descriptions within a company or organization will help keep them consistent and uniform in style and substance, as well as ensure a fair hiring process. Create a document that provides a snapshot of the company and the department, and then provides a space for the job duties and required qualifications related to each particular position.
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.
