This makes it possible to achieve a holistic view in the case study Norsk kvinnliga personer. The literature suggests some techniques for improving the quality and especially the validity in case studies (Yin, 2009). One of them is to use multiple sources of evidence in the data collection phase to increase the construct validity (Riege, 2003; Beverland and Lindgren, 2010). In this study, we have used field observations, internal documents combined with interviews. Yin (2009) argues that a second tactic is to establish a chain of evidence, which has been addressed by combining these different sources during the data collection procedure. One way of addressing internal validity is establishing phenomena in a credible way (Riege, 2003). In this study, we have used pattern matching to reach that qualitative criterion.
