For our research, first a survey was conducted as a quantitative method and then
supplemented by case studies in order to collect additional qualitative data. Surveys
have been criticized for over-simplification of reality, but they allow for statistical
generalization. This method was used to test the hypothesized effects of SCRM on
agility and robustness and further on performance. Interviews as part of case studies
have been criticized for their propensity to encourage interviewer and respondent bias,
but they represent a targeted method of collecting data and are often insightful
(Frankel et al., 2005). Here, this method is used, to build on survey findings presented to
the interviewees to reveal new knowledge about agility and robustness in the context
of SCRM. Most importantly, the integration of a survey with case studies combines the
advantages and minimizes the disadvantage of each method and allows the qualitative
refinement of the theory underlying the quantitative survey. Building on research
processes proposed by Spens and Kova´ cs (2006), deductive and inductive approaches
were combined in this research as is shown in Figure 1.
