This diagram illustrates the idea that problems often have more than one solution path. All connected solution paths are valid. There is no such thing as the best way, the right way, or the correct way. The various paths and branches are different ways of exploring the problem. They are different ways of coming to understand the problem.
Different paths provide different insights.
