BPM Methodologies and Process Maturity 

A business process methodology is a formal description of a procedure that a team can follow to redesign or improve a business process. Some prefer to describe such a procedure as a "framework" to suggest that it provides an overall description of how to proceed, but avoids being too prescriptive. Since we tend to use the term "framework" to refer to a template that can be used to define a set of processes, we prefer to speak of a set of procedural steps as a methodology, and then simply distinguish between more precise and less precise prescriptions. Another way of talking about the distinction is to discriminate between methodologies based on a detailed prescription and those based on heuristics or rules of thumb. Read more here.
