A decision point where available paths diverge significantly and the choice is difficult or impossible to reverse once committed. Strategic forks are high-stakes by definition — they create path dependency, meaning future options are constrained by today's choice.
Examples include entering a new market, choosing a technology platform, or accepting an acquisition offer. These decisions benefit most from structured multi-perspective analysis because the cost of getting them wrong is compounded over time, and the cognitive biases that plague individual decision-makers (anchoring, sunk cost, status quo) are at their most dangerous.
