4.2.2 Data analyses The interviews were analysed to find different “themes, patterns, trends and relationships,” (Mouton, 2009. p.108). The propositions were used to outline the important “themes”, events and “relationships,” (Mouton, 2009. p.108). The conversations were reviewed and items were grouped as per the order of the propositions. Careful consideration had to be given to the sequence of events and getting the timeline correct so as to ensure when different events occurred or when different initiatives took place. Thereafter the data was used for the purpose of “explanation building. To ‘explain’ a phenomenon is to stipulate a presumed set of causal links about ‘how’ or ‘why’ something happened. The better case studies are the ones in which the explanations have reflected some theoretically significant propositions,” (Yin, 2009, p.141). This study builds an explanation around the events that occurred over a period of time that could explain the performance of the business unit of a subsidiary. The propositions that were developed are based in theory and are used to explain the events as well as how the events and the theory are interrelated. This case study compares the financial information based on the interventions that the MD took which are the actual results as well as the financial results had the MD not intervened and not developed initiatives to attract new clients, this method of analysis is considered to be “time-series analysis” (Yin, 2009, p.141) and assists in the explanation building technique. 4.3 Assumptions Assumptions were made at the start; all assumptions were tested for validity through discussion and the review of business unit documentation. Assumptions that could not be proved through any form of evidence were abandoned. 4.4 Limitations For many the fact that only one in-depth case study was done is seen as a limitation, but it was mentioned that this study was not meant to be “generalizable to all populations but tries to explain only what is going on in one particular setting,” (Saunders and Lewis, 2012, p.128)
32 The bias of the interviewer is also a limitation; this risk was mitigated through corroborating ideas with the interviewees as well as following up on discrepancies and inconsistencies on information received from the different interviewees. Time was also a huge limitation, due to the busy schedules of the participants the interviews were often rushed and follow up appointments had to be made; this involved an even greater investment in terms of time.
