MECE (Mutually Exclusive, Collectively Exhaustive)
19 Jan 2022
MECE is a strategy used to break down large problems into sub-problems with "binary" solutions to allow easier thought on solving a problem.
Mutually Exclusive
- No Overlap between the Different Blocks of Trees
- Cannot Be True Simultaneously
Collectively Exhaustive
- Information in the blocks covers every possible option
If you draw an problem out with branches that are MECE, you can then talk about each one in isolation. This often helps to make a complicated problem easier to understand and solve.
