Data analysis was inductive and continued throughout the duration of the case study. It was informed by problem-based methodology (Robinson, 1993) in which the first step was to identify the taskforce’s key practices. Since we sought to explain those practices by connecting them to organizational norms existing in the school, we reconstructed the values, beliefs and practical considerations that underlay them. This reconstruction, summarized in Figure 1, took into account both the practitioners’ explanations of their practices and the frequently unstated beliefs and values that appeared to the researchers to underpin them. Given the possibility for error in this process, the accuracy of all reconstructions was checked with the relevant practitioners in feedback interviews.
