Process models are structured representations that outline the steps involved in a specific process. They help in understanding, analyzing, and improving workflows by providing a clear visual depiction of tasks, inputs, and outputs. Commonly used in fields like software development and business management, these models can take various forms, such as flowcharts or diagrams. In addition to enhancing clarity, process models facilitate communication among team members and stakeholders. They serve as a reference point for training and documentation, ensuring that everyone involved has a consistent understanding of the process. Popular methodologies that utilize process models include Business Process Model and Notation (BPMN) and Unified Modeling Language (UML).
