The specific job title is important because it differentiates one position from another. You will want to leave a space at the beginning of your job description template for the position title.
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.
