Let us begin with a proposition so banal that it passes, in boardrooms, for daring originality: most projects are approved on the understanding that reality will behave itself. The Best Case Scenario—capitalized, canonized, and deified—is treated as the baseline, as if Fortune herself had joined the payroll. One could call this optimism. One could also call it, with greater accuracy, a cult of false hope.
It Usually Starts off Well
A conscientious project manager, the sort who still believes numbers mean something, will dutifully inventory features, tasks, effort, time, and cost. She will even do the unfashionable thing: risk analysis. That tiresome discipline asks what might go wrong, how likely it is to do so, how hard it will bite when it does, and what mitigations cost.
From this arithmetic of contingency, two bookends emerge.
-
-
Best Case: nothing untoward happens; all risk remains theoretical, pristinely inert.
-
Worst Case: the entire rogues’ gallery of risks strolls onstage, plus a few latecomers you were too innocent to imagine.
