Is there a right way to prepare a process diagram? There are many books and papers about what is the best way to diagram a process, what symbols to use, how to connect processes, what the BPMN2 standard is about, how to elicit process requirements, applying simulation for improvement or the more traditional observation method all very useful. There are few books or articles that really show how the various styles and types of maps and models fit and connect together. The relationship of various layers and scopes of processes, why you do them and how they connect together is what is important.
