We’ve talked a few times about being mutually exclusive and collectively exhaustive (or MECE) in your thinking:
First, we talked about how MECE thinking is useful because it helps ensure that your approach has no overlaps (ME) and no gaps (CE). Then we looked at ways to be more MECE in your thinking by being CEME. And we’ve also addressed the fundamental issue of MECE thinking in problem solving: that your true intent is not to find solutions that are truly mutually exclusive but rather independent because being ME requires a preclusion. So, rather, we introduced the idea that you should think about being ICE (independent and collectively exhaustive) instead. This seems to be confusing, so let’s see if we can clarify the whole thing.
