Strategy-Environment Fit
A strategy is good only for the environment whose constraints and incentives made it effective. Once those conditions change, repeating the winning formula can turn competence into a disadvantage.
Your most dangerous strategy may be the one that already proved it could win. Its success encourages repetition even after the world that rewarded it has disappeared.
E1Success preserves yesterday’s assumptions
Every strategy embeds a bet about its environment: which constraints matter, what others will do, and which actions receive the highest payoff. Success validates the strategy under those conditions, but it also makes the underlying bets less visible. You remember the formula and stop checking the world that made it work. When incentives, technology, or constraints shift, the payoff structure shifts with them; unchanged execution can then become actively inferior. This is Fighting the Last War at the level of strategy.
E1Change alone is not disproof
A changed environment does not automatically make every established strategy obsolete. The decisive question is narrower: did the change alter an assumption or payoff on which the strategy depends? Abandoning a sound approach merely because the surroundings look different is another form of poor fit.
E1Audit the condition behind the win
Take one strategy you still use because it worked before. Write down the environmental condition that made it pay off, then identify one observable sign that the condition still holds. If you cannot find that sign, treat the strategy as an untested hypothesis rather than a proven formula.
