Methodological note — read first
These twelve cases are composite teaching cases, in the method of the Harvard Business Review: built from recurring decision patterns in each sector, merged and anonymized to protect confidentiality. Names, figures and outcomes are illustrative and do not describe a single client engagement. The «sources» indicate the type of evidence the engine cites with provenance in production.
Why this way: inflating a track record would be the first error the method itself would flag. That is why no case carries a Δ-CSI score: a score is shown only when the complete, versioned scorecard can be reproduced. The strength of these cases is in the method.
