Your literature review is an overview of what has been written about your topic and helps put your research into context, which helps the reader understand it. Your first step is to follow your syllabus and your instructor's directions for choosing a problem in your workplace that you would like to research. Then you'll get background information that you will use to develop an overview of the history, issues, and solutions surrounding it.
Per your syllabus, your literature review needs to contain a minimum of three sources of information. Compared to most literature reviews, it will be very brief; however, if you would like an overview of literature reviews, the University of North Carolina, Chapel Hill, provides a good one.
