McKinsey MECE Structured Writing

Problem

Multi-point answers often become flat lists: the conclusion appears late, groups overlap, and hierarchy lacks order. McKinsey MECE Structured Writing is intended for reports, proposals, recommendations, and synthesis tasks, turning conclusion-first, top-down, MECE, and progressive logic into enforceable constraints.

How It Works

The skill first checks whether it should trigger. Simple facts, single-step operations, pure retrieval, or one-line requests are answered directly. When two or more logically connected points are required, it runs a three-step process: identify the problem type, select a construction path, and self-check the output. Core capabilities include SCQA framing, decomposition for root-cause, decision, workflow, and quantitative problems, induction or deduction ordering, and a problem → solution → validation chain for each dimension. It also checks for common anti-patterns: disconnected parent-child points, mixed classification criteria, mixed deduction and induction, and key sentences that are labels rather than claims.

Boundaries

It fits structured analysis better than pure narrative, casual chat, or single-sentence answers. If the result has three or more nested levels but only one core conclusion, more groups than needed, or a longer SCQA introduction than the body, the skill requires simplifying the output so the framework does not become redundancy.
