SLR Approach applied to SCM

#	Step	Steps in General SLR Guidelines (Tranfield et al. 2003)	Steps in an SCM Review (Durach et al. 2017)
1	Define the Research Question	- Justify review in terms of timeliness and relevance - Highlight contribution of SLR	- Develop an initial theoretical framework regarding the phenomenon under study to refine it considering the SLR literature
2	Decide required characteristics of primary studies	- Craft inclusion and exclusion criteria	- Develop criteria for determining whether a publication can provide information regarding the theoretical framework
3	Retrieve sample of potentially relevant literature (“baseline sample”)	- Decide search procedures - Define and apply keywords to retrieve a preliminary sample of primary studies.”	- Find literature through structured and rigorous searches
4	Select pertinent literature (“synthesis sample”)	- Apply inclusion and exclusion criteria	- Conduct theoretically driven selection of literature to identify relevant studies according to inclusion/exclusion criteria
5	Synthesise literature	- Apply coding schemes to extract pertinent information from the literature - Synthesise studies by summarising, integrating, or cumulating the different findings across the primary studies	- Develop two data extraction structures based on aspects of the first theoretical framework - Integrate data to refine the theoretical framework, that is, figure out what works for whom, how, and under what circumstances - Develop narrative propositions that explain the mechanism, context (moderating conditions), and outcomes
6	Result Reporting	- Report results from the review	- Explain the refined theoretical framework and compare with initial theoretical assumptions
