MECE

From DALL-E with some prompting
The image provides a visual explanation of design and algorithm optimization strategies based on the MECE principle, which stands for “Mutually Exclusive, Collectively Exhaustive.”

• In the blue area at the top (“Mutually Exclusive”), there’s content related to “Distinguish,” which signifies conditions that are clearly differentiated from one another. It includes binary code formats “0/1” and “00/01/10/11” as examples, representing distinct states. The pie chart beside it illustrates segments that are clearly separated, denoting distinct categories. Below is the phrase “One ‘if [Condition] then [Action]'”, suggesting that for a specific condition, one action is defined—akin to an “if” statement in programming.
• In the pink area at the bottom (“Collectively Exhaustive”), there’s content related to “Unify.” This implies the inclusion of all possibilities by using many “if~” statements for all conditions. The word “All” emphasizes encompassing and including every condition. The circular chart beside it shows various pieces coming together to complete a circle, representing completeness when all parts are combined.

The overall context suggests applying the MECE principle in programming or system design to distinctly separate mutually exclusive conditions (as shown in the top blue area) and to comprehensively address all possible conditions (as indicated in the bottom pink area) to ensure the entire system or program functions comprehensively. The statement “Start a design with (before coding) MECE. Do Algorithms & optimizations with ‘Necessary and sufficient conditions’.” advises to apply the MECE principle when starting a design and to consider necessary and sufficient conditions when working on algorithms and optimizations.
