Case law for strategy.

Strategy Decision Cases

Every strategic decision belongs to its own company, market and moment. What sharpens the call is evidence of how others met similar pressure and what it cost them. These cases are that evidence: what was on the table, what the company chose, and what it returned, with every field sourced.

This measures whether a decision STUCK, not whether it worked. A decision counts as held when the company never undid it — BlackBerry's refusal to take BBM off its own handsets held, and BlackBerry went to 0.5% of the smartphone market. Held over settled: 825 records whose verdict is in, from forks between 1891–2026, with 54 still too early to call and counted in neither. It is what happened to the companies on record, not the odds for your decision: the corpus covers decisions documented well enough to verify, which skews toward companies that lasted long enough to be written about.
