Using Optionality to Improve Real‑World Decision‑Making

 Decision‑making under uncertainty often requires more than choosing a single path. By recognizing the value of optionality, leaders can navigate ambiguity with greater clarity and strategic flexibility. The following model outlines key elements that influence how choices evolve when conditions are unpredictable.
