What is the purpose of using annotations in process models?

Annotations in process models serve the primary purpose of helping other designers understand the design. By including annotations, designers can provide context, explanations, or comments that clarify the intentions behind specific processes or elements in the model. This is particularly valuable in collaborative environments, where multiple designers might be working on or reviewing the same process model.

While some annotations may visually enhance a model or contribute to aesthetic aspects, their core function is to communicate and convey important information to anyone who interacts with the model in the future. Thus, annotations become a crucial tool for maintaining clarity and promoting effective collaboration, making them essential for team-based development and model maintenance.
