InfoQ: Why would I want a workflow engine in my application?
Diego Naya Lazo: Most business applications today mimic a real life business process. This process is made up activities and transitions between those activities.
A workflow engine enables the developer to model a business process and allows the application to go with the flow of information defined by the process.

InfoQ: What is the difference between a workflow and a series of business rules?
Diego Naya Lazo: In the strictest sense a workflow and a rule are pretty much the same. A workflow is a series of steps that you want a user to follow, but according to some business logic. This logic are best represented with rules.
So, a workflow usually embeds business rules at each step. The rules themselves can be nested workflows.
