What is a risk trigger and why is it important to identify?

A risk trigger, also called a risk symptom or warning sign, is an event or condition that indicates a risk is about to occur or has already occurred. Identifying triggers is important because they serve as early warning signals that activate the planned risk response. For example, a vendor consistently missing minor milestones might be a trigger that the vendor will miss the critical delivery date. Triggers are documented in the risk register alongside the associated risk and response plan. ---
