A systematic review...
Your Academic Liaison Librarian can give advice on some of the steps in the process, such as choosing where to search (step 2), developing a search strategy (step 3), running & recording your search (step 4) and managing your search results (step 5). Refer to your supervisor for help with developing your protocol, evaluating the studies and writing up the review.
You may be asked to do a systematic review, when what they actually want you to do is a systematic review of the literature. There are few key differences.
|Systematic review||Systematic literature review|
|Brings together the results of studies to answer a specific question||Provides a subjective summary of the literature on a topic|
|Extensive search covering published and grey literature||Thorough search of published literature|
|Involves a detailed protocol often developed using the PICO framework||Includes a detailed search strategy|
|Usually involves three or more people to eliminate bias||Can be produced by a single person, so open to bias|
|Can take months or years to produce||Weeks or months to produce|

There are many other types of review a few of which are outlined below. Many of the steps in this guide will still be relevant for other reviews, it might just be the way you synthesise the results which is different. For a more comprehensive overview of review types see the page below from Duke University:
An initial assessment of the size and scope of research literature on a topic. Can be the first step in a systematic review.
Uses systematic review methods to search and critically appraise existing research to find out what is already known about a topic.
A statistical approach to combining the data derived from from studies retrieved by a systematic review.
Uses description rather than statistics to analyse the findings from relevant primary studies.
The following videos offer two explanations of systematic reviews and what's involved in doing them.
