## 1. Upstream Project

| Field | Value |
| --- | --- |
| **Project** | mckinsey-consultant-skills (V3.1) |
| **Maintainer** | @Kafurtan |
| **GitHub URL** | <https://github.com/Kafurtan/mckinsey-consultant-skills> |
| **License** | **MIT License** |
| **Form** | AI agent skill (`SKILL.md` + `references/`) |
| **Content** | An 8-step workflow that automates "business problem → McKinsey-style presentation," end-to-end in 90-110 minutes |

## 2. What mckinsey-consultant-skills Is

It systematizes McKinsey's Problem Solving methodology into an **8-step workflow** that lets an AI assistant turn a business problem into a professional presentation (PPT + Excel evidence trail).

### Structural Features

- **8-step workflow**: define boundaries → Issue Tree + hypotheses → Dummy Pages + design specs → page-by-page iterative production → PPT + Excel → optional Word report → iterative revision.
- **Dummy Page**: build the wireframe spec before research, to avoid aimless data collection and to support resuming across conversations.
- **Dependency awareness**: pages are tagged with dependency status, determining production order (the executive summary is done last).
- **7 page layouts**: title + single chart / two-column / 2×2 matrix / table / waterfall chart / timeline / insight summary.
- **Excel evidence trail**: per-page raw data + URL + cleaning process.
- **Progressive disclosure**: reference files are loaded only at the steps that need them and released afterward, saving ~70% context.
- `references/`: methodology.md, layouts.md, design-specs.md, examples.md, troubleshooting.md.

## 3. What We Adapted and Cited

| Scope | Treatment |
| --- | --- |
| **The 8-step production workflow** | Referenced the workflow, rewritten in this methodology's language, mapped to the eight-stage consulting structure |
| **The Dummy Page concept** | Adapted the "skeleton-first, fill-in-later" discipline into per-page specs for this methodology's deck outlines |
| **Dependency awareness** | Adapted the page-dependency-management concept |
| **The 7 page layouts** | Referenced the layout list, rewritten to extend `VISUAL_ASSETS_SPEC.md` |
| **Excel evidence trail, progressive disclosure** | Adapted the concepts, mapped to this methodology's Evidence discipline and AI-IDE context management |
| **McKinsey Problem Solving, MECE, Pyramid Principle** | Public-domain management knowledge, not proprietary to this project |
| **The original `SKILL.md` and `references/` files** | **Not reproduced, not forked**; this methodology is an independent rewrite |
