What is a process model?

A business process model clearly shows the steps by which work is done—extremely helpful when evaluating or changing business processes. Having a clear model of the repeatable steps of the workflow makes it easier to identify gaps and suggest changes. If analysis determines that the process isn't repeatable, is inefficient, or is imperfectly linked to other parts of the solution, the process model also gives you a way to document what the process should look like in the future, compared to how it looks today. The process model can help you communicate the requirements for each process, while the project moves from the current, "as-is" state to the goal, "to-be" state.
