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

An example of mutually exclusive

Collectively Exhaustive

  • Information in the blocks covers every possible option

An example of collectively exhaustive

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.
