The short version

MECE stands for Mutually Exclusive, Collectively Exhaustive. In plain English: no overlaps, no gaps.

If you split costs into 'people', 'technology' and 'software', you've got an overlap, because software is technology. If you split customers into 'new' and 'loyal', you've got a gap: what about customers who are neither?

You won't always get a perfect split. That's fine. The point is to check, because overlaps waste effort and gaps hide the answer.

Try it now. Put this into practice with the MECE Checker (coming soon).
