 Contingency - the budget allocated to the contingent response

Trigger - an event that itself results in the risk event occurring (for example the risk event might be "flooding" and "heavy rainfall" the trigger)

Although risk registers are commonly used tools not only in projects and programs but also in companies, research has found that they can lead to dysfunctions, for instance Toyota's risk register listed reputation risks caused by Prius' malfunctions but the company failed to take action.Risk registers often lead to ritualistic decision-making, illusion of control, and the fallacy of misplaced concreteness
