How to understand the above image? Start from 4.1 Develop project charter then start moving downwards until you encounter another process in the Initiating process group. So 4.1 will be followed by 10.1 Identify stake holders, however once you reach the end you can start from the next process group's top. So 10.1 will be followed by 4.2 develop project plan. So on and so forth.
