For instance, if you implemented an instance of Recursion but need to break up the task among multiple objects, the arrow labeled different object points you directly to Redirected Recursion. If instead you find that the Recursion needs to be broken up into distinct subtasks, then you will be introducing new methods, and you know that you will no longer retain the method similarity. In that case, the large arrow in the middle labeled dissimilar method indicates you should slide left to the corresponding location on that tree, and you end up at Conglomeration. Each decision point that you have at your disposal will lead you to the proper, related concept
Best methodology I've seen yet for approaching refactoring in a concise paragraph.
