In this article, Lloyd Atkinson explains how modelling workflows with finite state machines can help simplify complex workflows in .NET. He introduces the concept of finite state machines and provides an example of a document workflow that requires approval from multiple stakeholders. He highlights the problem with representing workflows as dozens or hundreds of flags, and the challenges they present in testing, maintenance, and refactoring. By demonstrating the benefits of using finite state machines, Lloyd shows how we can shift more of the business logic into the type system and improve code maintainability.
