Pressure does not simply make performance worse. It changes its character — revealing capabilities that normal conditions conceal and degrading others that normal conditions support.
The Pressure Effect on Performance
Pressure — the condition in which the stakes are high, the time is limited, the consequences of failure are severe, and the cognitive resources available are reduced by the stress that these conditions produce — changes institutional and individual performance in ways that are more complex than the simple degradation model suggests. Some capabilities are enhanced under pressure: the focus that pressure produces can improve performance on well-learned tasks by eliminating the cognitive interference of non-essential processing. Some capabilities are degraded: the cognitive load of the stress response reduces the working memory and executive function capacity that complex decision-making requires. And some capabilities are revealed: the pressure situation removes the ability to perform for an audience in ways that conceal actual capability, and the performance that emerges under genuine pressure is a more accurate representation of actual capability than the performance that normal conditions produce.
The practical implication is that pre-pressure performance measurement is an imperfect predictor of under-pressure performance, in ways that vary by the specific capabilities being measured. The leader who performs brilliantly in the measured, deliberate conditions of normal operation may perform very differently when facing the time pressure, incomplete information, and high stakes of genuine crisis. The team that coordinates smoothly in the rehearsed, structured conditions of normal operation may coordinate very differently in the improvised, stressed conditions of genuine disruption.
Developing Pressure Performance
Developing institutional performance under pressure requires exposing the institution's decision-making and coordination processes to conditions that approximate the pressure characteristics of the scenarios they will face — not just the content of those scenarios but their time pressure, their informational incompleteness, and their stakes. The training that presents the relevant scenarios without the relevant pressure develops content knowledge without developing the performance capabilities that pressure conditions require. The training that reproduces the pressure as well as the content develops both.
Pressure reveals what normal conditions conceal. The capabilities that hold under genuine pressure are the institution's actual capabilities. The capabilities that degrade are its performed capabilities — the performance quality that rehearsal and optimal conditions produce, which will not be available when the conditions are neither optimal nor rehearsed.
