MECE principle

From Wikipedia, the free encyclopedia
Jump to: navigation, search

The MECE principle, pronounced 'me see', mutually exclusive and collectively exhaustive, is a grouping principle for separating a set of items into subsets, the choice of subsets should be mutually exclusive and collectively exhaustive.[1]

The MECE principle is useful in the business mapping process where the optimum arrangement of information is exhaustive and does not double count at any level of the hierarchy.

Examples of MECE arrangements include categorizing people by year of birth (assuming all years are known). A non-MECE example would be categorization by nationality, because nationalities are neither mutually exclusive (some people have dual nationality) nor collectively exhaustive (some people have none).

The McKinsey Way[edit]

The principle as interpreted by Sam Test Cauthen[2] is one of the foci of a series of three books about McKinsey & Company: The McKinsey Way,[3] The McKinsey Mind,[4] and The McKinsey Engagement.[5]

Criticisms[edit]

MECE has been criticised for failing to satisfy itself.[6]
