A job description is a written document that should include the employee's duties, responsibilities and outcomes needed from that position. It should also include the required qualifications and reporting relationship.
If your employee has a poorly written job description, or one that is out-of-date, it will lead to confusion and misunderstandings.
Once you have a job description for each employee, you'll be able to ensure the descriptions all fit together logically and leave no holes in the duties that need to be assigned.
Check your job descriptions at least yearly to be sure they reflect the employee's proper title and current duties. Very often employees get new job titles or are assigned new tasks mid-year, and those don't get reflected in their job descriptions. Don't let that happen.
Finally, if you don't have access to a Human Resources department that can help you craft your job descriptions you can find lots of good examples online.
