Prepare job summaries, if relevant. You can use the job description template you use for each position that you advertise by filling in the template with the information that is relevant to that position. However, if you do (or expect to do) a lot of hiring of a particular position, you might make a special template that includes a summary of that job. This will save you some time.
Specify how the position fits into the organization. Indicate who the job reports to and how the person will function within your organization, helping candidates see the bigger picture and understand how the role impacts the business.
