All diagnostic and treatment activities have been recorded for these patients. Clearly, this is a Spaghetti process. However, as shown in [64] it is possible to create simple models for homogeneous groups of patients using the hierarchical clustering technique illustrated by Fig. 12.7. The same event log also contained information about resources. For instance, Fig. 12.13 shows a social network based on this log. As in earlier examples, the social network is based on handovers of work. However, now we do not look at individuals but at the level of organizational units. Figure 12.13 can be used to analyze the flow of work between different departments of the AMC hospital.
