Systematic reviews of the literature are complex projects that require the input of numerous people over a period of time.
Some elements are specifically related to library research skills, while others delve more into research methods, data analysis and other, necessary, skills which sit outside the purview of the library. For this reason, you won't find all elements of a systematic review described here.
For fuller details it's recommended that you look at the variety of resources which describe the different stages of systematic reviews and incorporate the elements which seem relevant to your particular review into your organisational chart.
