We used multiple methods in the study to improve the reliability and validity of the data collected, culminating in the collection of a rich set of data (triangulation). Multi-methods research was designed to guarantee the reliability and validity of quantitative measures (Romm & Ngulube in press). An embedded case-study design offered the opportunity to explore in depth the extent to which banks have implemented KM practices such as the acquisition, sharing and retention of knowledge. Embedded case studies are studies in which different levels or sources of data are collected (Yin 2003 ). According to Powell ( 1997 :66), the population should be selected with great care, bearing in mind the selection criteria, the desired size and the parameters of the survey. In light of the above, we selected two commercial banks from the four commercial banks in South Africa (population) but then targeted middle managers and purposively selected senior-level managers from the population. The population of a study is the group about whom one wants to draw conclusions. In this case, it was all middle-level managers and purposively selected executive managers (Babbie 2010 :111). The whole population (190) of middle-level managers was considered in the study whilst four senior executives were purposively selected to participate in face-to-face interviews. These were selected from the already-delineated sample perceived by the researchers to be key individuals who would give invaluable insight and more detailed answers to the research questions on KM policies.
