# MECE (Mutually Exclusive, Collectively Exhaustive)

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.
