The first step toward ultimately exploding or levelling a process is to identify the internal processes that will become visible on a more detailed Data Flow Diagram. The problem is that a detailed DFD should never have more than 7 plus/minus 2 processes. How do you know which processes to represent? In lectures 7-9 you will learn how to identify the "RIGHT" Processes for a Data Flow Diagram (DFD). Lectures 7-9 answer questions like: • What does “exploding a process” mean? • What is the business value of doing it? • What processes will the lower level diagram contain?
