McKinsey Critic

Reviews your work the way a McKinsey engagement manager would at 2am before a client presentation. Catches structural problems, weak arguments, missing data, and logical gaps — then tells you exactly what to fix.

How It Works

Give the critic any deck outline, strategy document, memo, or recommendation. It will:

  • Grade the overall work (Green / Yellow / Red)
  • Review each section or slide with a status and specific issue
  • Identify the top 3 fixes — ranked by impact, with clear instructions
  • Call out one thing that works — so you know what to protect

Grading Scale

| Grade | Meaning |

|-------|---------|

| Green | Ready for stakeholders. Minor polish only. |

| Yellow | Fixable overnight, but do not send as-is. Structural issues that undermine credibility. |

| Red | Needs rework. Core argument or structure is broken. |

What the Critic Checks

Structure

  • Does the narrative flow logically? (Problem → Context → Analysis → Solution)
  • Are section breaks in the right place?
  • Is there a clear beginning, middle, and end?

Rigor

  • Is every claim backed by data or a source?
  • Are numbers specific, not vague ("grew significantly" → "grew 25% YoY")?
  • Are comparisons fair and complete?
  • Is there a financial frame where one is needed?

So-What

  • Does each section have a clear takeaway?
  • Can someone read just the titles/headers and understand the full argument?
  • Is the recommendation actionable and time-bound?

Completeness

  • Are there comparison frameworks where options are presented? (not just a list)
  • Are competitors named, not described generically?
  • Are next steps specific with owners and timelines?

Common Problems the Critic Catches

  • Topic titles instead of claim titles — "Market Overview" vs "Global coffee market will reach $373B by 2030"
  • Lists where frameworks belong — three options as bullets vs a comparison table with dimensions
  • Missing financial frame — recommendations without revenue/cost/investment sizing
  • Unsourced statistics — numbers without citations destroy credibility
  • Structural errors — solution content in the problem section, complication slides after resolution
  • Vague recommendations — "allocate resources" instead of "$15-25M Phase 1 investment over 12 months"
  • No "so what" — data presented without interpretation or implication

When to Use

  • After building a deck (with Storyline Builder or any other method)
  • Before sending a strategy document to leadership
  • When reviewing a team member's work
  • After writing a memo or recommendation
  • Any time work needs to survive a senior audience

Tips

  • Run the critic BEFORE you polish formatting. Fix structure first, then make it pretty.
  • The top 3 fixes are ranked by impact. If you only have time for one fix, do Fix 1.
  • Yellow is the most common grade. That's expected — it means the thinking is right but the execution needs tightening.
  • Pair with the Storyline Builder. Build the narrative first, then let the critic review it.
