3 Coding the articles subject to content analysis by visually scanning the entire document for discussions of conceptual frameworks. Data were recorded in an Excel theory and spreadsheet.. The panel and an additional four OM researchers coded the papers researchers went through initial learning period samples of coded papers were swapped and re-coded by members of the research team to see if there was agreement. The lead researcher randomly chose a sample of papers from each researcher, coded them independently, and then discussed any further anomalies with the researchers, After this process, the inter-rater reliability of coding using the categories was found to be 79 percent, which is an acceptable level of agreement (Carey et al, 1996) Articles were scanned for any discussions of theory, usually found in the literature review or front part of the article. If the article was available electronically as a Portable Document Format (PDF file, an additional search for theory was condocted by typing theory" and "theoretical" into Adobe Readers "Find" search bar. Instances in which one theory was dominant were recorded, and where several theories were combined in a study e attempted to identify the dominant theory in the collection, if possible, and recorded the additional theories
