SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Strategy analysis of a real company often drifts into storytelling without evidence: runaway narratives, ungraded bets, and acquisition claims accepted at face value. This Skill supplies fourteen distilled concept notes from Aswath Damodaran's teaching on narrative and numbers, giving the analyst base rates, screens, and procedures to grade every strategic claim by evidence. ## Core Features & Use Cases - Fourteen concept notes as on-demand references: Each note follows the same shape — core idea, formulas, a numbered procedure, reference data, and a worked example — covering bias declaration, runaway stories, life-cycle staging, possible/plausible/probable grading, big-market-delusion tests, acquisition empirics, synergy delivery odds, and objective-function audits. - Strategist report skeleton: A Markdown template for the full strategist report, from executive brief through bets, tactics, operational surface, and verdict, with placeholders to fill. - Use Case: When auditing a company's claimed synergy from an acquisition, load the synergy-delivery-odds note to apply the McKinsey realization base rates (70% of mergers miss revenue synergies), haircut revenue synergies for customer attrition, and score the deal against the seven-sins checklist. ## Quick Start Load the runaway-stories note from this skill and use its three-ingredient screen to assess whether the company narrative I describe is at risk of being a runaway story.

Frequently Asked Questions about strategy-concept-notes

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I grade a company's strategic bets by evidence?

Use the possible-plausible-probable note: classify each claim by whether you can assign it a probability, then route it accordingly — probable claims go into base numbers, plausible claims into expected growth, and possible claims into option value. Write down the evidence trigger that would promote each grade.

How do I test whether a market-size claim is realistic?

Apply the big-market-delusion test: impute the revenue each competitor's valuation requires, sum across all players including foreign ones, and compare the total against a credible market forecast. If implied shares exceed 100%, the sector story is collectively impossible.

What base rates exist for acquisition success and synergy delivery?

The notes cite announcement returns of roughly +17% to +19% for targets versus about zero for acquirers, McKinsey findings that 70% of mergers miss revenue synergies while most hit cost savings, and divestiture rates near 50% over ten years. Quote each figure with its vintage as a prior, not a fact about the specific deal.

Does this skill compute valuations or run financial models?

No. It contains no scripts and computes nothing; it is a library of reference notes loaded one at a time. Where a note references DCF inputs, you translate them to the strategy question rather than building a model.

When should I not rely on the numbers in these notes?

The figures are priors from dated source material, mostly 2014 to 2021 lecture decks. Cite them as base rates with their vintage, never as current facts about the company under analysis, and update them when newer evidence exists.
