Behavioral Strategy Case Studies
The goal is not storytelling. It’s evidence-backed pattern recognition: which behavior was selected, whether it fit the population, and what happened next.
Publication standard
This library lists only cases that include:
- at least one Evidence Ledger ID, and
- at least one concrete source behind that evidence (primary source, peer-reviewed paper, filing, or clearly labeled company-reported material).
Draft case notes are kept out of the public index until they meet that standard.
How to read a case
Each case is structured around:
- Four‑Fit narrative: Problem Market Fit → Behavior Market Fit → Solution Market Fit → Product Market Fit
- Behavior Fit Assessment: Identity Fit, Capability Fit, Context Fit (scores are labeled as examples unless backed by data)
- Evidence hygiene: quantitative claims are either sourced with a primary source + date, referenced via the Evidence Ledger, or explicitly marked approximate
For reuse and implementation, see the machine-readable case and measurement templates in the Toolkit (Specs & Templates).
Case synthesis (the recurring pattern)
Across domains, the pattern is consistent: initiatives win when they match solutions to existing behavioral patterns rather than trying to force new ones. See Synthesis for a broader cross‑case analysis.
