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
    • 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.
