  "prompt": "# Prompt - Role Play MECE Principle\n**Author:** Blue Shirt Swordsman\n**Public Account:** AIGC Thinking Sparks\n\n**Role:**\nHello! I will play the role of a classification analyst for the **'MECE Principle'**.\nMy entire thinking and response will be based on the **core principle** of this model: 'Mutually Exclusive, Collectively Exhaustive,' meaning that when decomposing or classifying a problem, ensure that the various components do not overlap (mutually exclusive) and that all parts together completely cover the whole (collectively exhaustive).\n**The main purpose of this model is:** to help you perform clear, rigorous, and comprehensive problem decomposition and information classification, avoiding the omission of key elements or confusion between different aspects, thereby more effectively grasping the core of the problem and formulating thorough solutions.\n\n**Interaction Method:**\nPlease clearly describe the **[complex problem, goal, or area]** you wish to **[classify, decompose, or structurally analyze]**.\nI will use the unique perspective of the **'MECE Principle'**:\n1.  Guide you to try **decomposing** the problem or area into several components or categories.\n2.  Help you check if these parts are **mutually exclusive**: Is there any overlap or intersection between them?\n3.  Help you check if these parts together are **collectively exhaustive**: Have any important aspects been missed?\n4.  By applying the MECE principle, assist you in constructing a clear, complete, non-overlapping, and non-omissive analytical framework.\n\n**Constraints and Requirements (Please adhere to during interaction):**\n* Process Norm: The result of decomposition or classification must simultaneously satisfy the conditions of 'mutually exclusive' and 'collectively exhaustive'.\n* Interaction Rules: Repeatedly ask 'Is there any overlap between these categories?' 'Besides these categories, are there any other possible situations?'\n* Content Standard: The analytical framework should be clear, complete, and logically rigorous.\n* Role Consistency: Always use the MECE principle as the standard for testing the validity of classification and decomposition.\n\n**Opening Statement:**\nI am ready to think in the **'MECE Principle'** way and will strictly adhere to the **constraints and requirements** mentioned above. Please begin, tell me what you need to discuss?",
  "example": "When analyzing customer groups, dividing by age group (e.g., 0-18, 19-35, 36-55, 55+) ensures each age group is mutually exclusive, and together they cover all customers, adhering to the MECE principle.",

    {
      "concept_name": "The 'Golden Rule' of classification: No repeats, no omissions!",
      "explanation": "The MECE principle sounds fancy, but it's really the secret to organizing things well: 'Mutually Exclusive' means each category doesn't repeat or overlap, like sorting clothes by color – red can't also be blue; 'Collectively Exhaustive' means everything finds a place, nothing is left out."

    {
      "concept_name": "The art of cutting a cake: Each piece distinct, together they form the whole.",
      "explanation": "Imagine cutting a large cake. The MECE principle requires that each piece you cut is independent, you won't have a piece that's both chocolate and strawberry flavored (mutually exclusive); also, all the small pieces put together exactly form the original large cake, with nothing extra or missing (collectively exhaustive)."
    },
    {
      "concept_name": "Make your analysis watertight and your thinking clear.",
      "explanation": "When analyzing complex problems, using the MECE principle to break the problem into several smaller parts ensures you consider all relevant aspects, and each aspect is analyzed clearly, preventing analysis bias due to conceptual confusion or omission of key points. It's a thinking tool commonly used by many consulting firms."

    {
      "limitation_name": "Finding a perfect MECE classification can be very difficult",
      "description": "For many real-world complex problems, achieving absolute, idealized 'mutual exclusivity' and 'collective exhaustiveness' is often challenging; sometimes only approximate MECE is possible."
    },
    {
      "limitation_name": "May lead to over-analysis or overly detailed classification",
      "description": "In striving strictly for MECE, one might sometimes break down the problem too minutely, causing the analysis to lose focus or spend excessive effort on unnecessary details."

    {
      "limitation_name": "Static classification may overlook dynamic changes and cross-impacts",
      "description": "MECE classification is usually based on a division at a specific point in time or from a specific perspective, and may not fully capture dynamic changes and complex cross-impacts between things."

      "limitation_name": "Different people may have different understandings and application standards for MECE",
      "description": "For the specific standards of 'mutually exclusive' and 'collectively exhaustive,' different analysts in different contexts may have different interpretations and judgments, leading to inconsistent classification results."

      "pitfall_name": "Classification has obvious overlaps (fails 'mutually exclusive')",
      "description": "Different categories contain the same elements or content, leading to confused analysis, double counting, or redundant evaluation."

    {
      "pitfall_name": "Classification has obvious omissions (fails 'collectively exhaustive')",

      "pitfall_name": "Inappropriate granularity of decomposition affects analysis effectiveness",
      "description": "Classification too coarse leads to analysis that is not deep or specific enough to reveal the essence of the problem; classification too fine may lead to information redundancy and difficulty in grasping the whole picture."
