The mechanism
A decision gate is a defined checkpoint at which a programme, investment or process must present specified evidence to a named decision authority before further money or resources are released. A functioning gate has three properties: criteria agreed before the work reaches it, an authority genuinely able to say no, and live options other than proceed, including stop.
Why it matters when money is moving
Gates exist because large commitments are made under uncertainty that only resolves over time. Staging the decision converts one irreversible approval into a series of smaller, better-informed ones, but only if each gate is real. The test is behavioural: if nobody can recall a programme being redirected or stopped at this gate, it is not a decision point. It is a progress ritual, and the organisation is carrying full commitment risk while believing it has staged it.
