What I've discovered through the years is that no matter how large or small a project or which tools are used, there are six simple best practices that you can use to make business process management a heck of a lot easier to handle. You might have a few of your own that you consider essential, but for me, the six best practices are:

Use a phased methodology.
Develop a process documentation guide.
Create a decision matrix.
Simulate, model, and test.
Communicate effectively.
Monitor the processes.
