Process models are simplified representations of complex processes, used to understand, analyze, and improve workflows. They help visualize the steps involved, the sequence of activities, and the interactions between different components. Commonly used in fields like business, software development, and manufacturing, these models can take various forms, such as flowcharts or diagrams. By providing a clear framework, process models facilitate communication among team members and stakeholders. They can identify inefficiencies, bottlenecks, and areas for improvement, ultimately leading to enhanced productivity and effectiveness. Tools like Business Process Model and Notation (BPMN) are often employed to create standardized process models.
