MECE Principle in Communication

Introduction

  • Leading consulting firms (e.g., BCG, Bain, Big 4) focus heavily on training new consultants, especially in communication.
  • Communication is deemed crucial in the business world and often lacking in young graduates.
  • Today's topic: MECE Principle (Mutually Exclusive, Collectively Exhaustive)
  • Relevant for both oral and written communication.
  • Includes practical exercises for improving written communication.

What is MECE?

  • MECE: An acronym for Mutually Exclusive, Collectively Exhaustive.
  • Mutually Exclusive: Different parts should not overlap.
  • Collectively Exhaustive: Several parts together should form the whole.

Importance of MECE in Consulting

  • Regularly part of consulting training curricula.
  • Memes highlight its significance
    • E.g., "MECE all the things", "Framework not MECE? I am disappointed.", "You had me at MECE."

Understanding MECE Through Examples

Simple Example: Circle Decomposition

  • Breaking down a circle into mutually exclusive and collectively exhaustive parts.
  • Parts do not overlap and collectively sum up to the whole circle.

Everyday Example: Card Collection

  • Organizing a trading card collection by color.
    • Mutually Exclusive: Each card belongs to one pocket (color).
    • Collectively Exhaustive: All cards are sorted into these pockets.

Practical Application: Cost-Cutting Project Example

Scenario

  • Task: Size the cost reduction potential and develop measures to implement these reductions.
  • Areas: Production, Sales, Purchasing, Overhead.

Drafting a Progress Report Outline

Example 1 (Flawed)

  1. Sizing Savings Potential
    • Benchmark analysis, etc.
  2. Low Hanging Fruits Measures
    • Production, Sales, Purchasing
  3. Savings Measures
    • Production, Sales, Purchasing
  4. Proposed Project Plan

Issues:

  • Overlap: Sections 2 and 3 talk about savings measures (not Mutually Exclusive).
  • Missing: Overhead is not addressed (not Collectively Exhaustive).

Example 2 (Improved)

  1. Sizing Savings Potential
    • Conducted analysis, Results per business function.
  2. Production
    • Short term measures, Medium term measures.
  3. Sales
    • Short term measures, Medium term measures.
  4. Purchasing and Overhead
    • Short term measures, Medium term measures.
  5. Proposed Project Plan

Benefits:
