In an actual company, some of the processes might be managed by the same person. Thus, for example, there might only be one manager for both scheduling and delivering pizzas and the analysis could be modified to reflect that.
If we create a swimlane diagram, then we usually represent the management of processes and subprocesses on the left vertical axis. In essence, a lane is within the responsibility of a manager. Depending on the level of detail we allow ourselves, we might only show a process or department manager, but in Figure 11.3, we have shown each of the subprocess managers.
By adding to the structure of the swimlane diagram, we can picture the hierarchical relationship between the manager of the food preparation process and the manager of the entire Pizza Delivery process.
