The best way to create and manage consistent, concise and effective job descriptions is to start with best-practice job description templates. A well designed template ensures employees, managers, HR and the organization overall get all the information they need, while making the associated tasks easier for everyone.
Typically, organizations use their human resources or personnel department to create job description templates. In some cases however, a departmental group, a manager, or another individual (usually the direct supervisor of a position) might be responsible for creating one. In any case, make sure the creator of the template is familiar with the company’s or organization’s needs.
