What aspect differentiates a Process Instance from a Process Model?

A Process Instance is distinctively characterized as the occurrence of a particular run of a defined Process Model. When a Process Model is designed, it serves as a blueprint that outlines the workflow, steps, and tasks required for a process. However, when that Process Model is executed, it generates a Process Instance, which is the real-time execution of the defined behaviors and tasks as outlined in the model. Each time this model is instantiated, it generates a new Process Instance, reflecting the unique data and context of that execution.

This differentiation is crucial; while the Process Model remains static, the Process Instance is dynamic and can change over time based on the execution context and the decisions made during the process. Understanding this distinction is vital for designing and managing workflows effectively within Appian.
