After that, someone will eat the meal and have his or her hunger satisfied. We would say “acquire groceries,” for example, not “first take care of shopping for groceries. It is totally up to the purpose of the model and therefore a decision the modeler has to make, whether a collaboration diagram with different pools is useful, or whether one should stick to one pool with different lanes, as shown in the previous chapter.
