Pressure

David Haig
2014

David Haig's play dramatises the 1944 confrontation between Scottish meteorologist James Stagg and General Eisenhower over whether weather conditions would permit the D-Day landings — a decision where imperfect data, institutional pressure, and irreversible consequences collided in real time.

For product directors, this is a case study in the authority of expertise against the authority of command: Stagg had the models, Eisenhower had the mandate, and neither could proceed without the other.

The drama exposes how forecasting under uncertainty is not merely technical but political — the forecast must be believed as well as correct, and credibility is a resource that can be spent or squandered.

Haig captures how high-stakes decisions compress time, distort communication, and force a reckoning with what 'confidence' actually means when the margin for error is zero.

Product teams routinely face structurally similar moments: shipping on uncertain data, advising leaders who hold more power but less context, and bearing responsibility for outcomes they cannot fully control.

The work is a precise moral argument for rigor, intellectual honesty, and the discipline of saying what you actually know.
