Final answer:
A pool represents a process participant in the context of process mapping and business process modeling, specifically in Business Process Model Notation (BPMN). It illustrates different entities or business units responsible for sets of activities within a larger process. So, the best answer is 2, process model.
Step-by-step explanation:
In the context typically used in process mapping and business process modeling, a pool represents a process participant.
This term is often associated with Business Process Model Notation (BPMN), which is a method for illustrating business processes in the form of a diagram. In BPMN, a pool is a graphical container for partitioning a set of activities from other pools, mainly to illustrate different entities or business units in a process.
For example, in a diagram illustrating the process of product development, there may be separate pools for the marketing team, engineering team, and manufacturing team, each responsible for different stages and activities within the overall process.
A pool is thus not merely an activity or a role; it encapsulates the entire set of processes that a participant or an organizational unit is responsible for. By understanding these concepts, one can better design a process, build models, and solve problems in an organizational context.
So, the best answer is 2, process model.
