When there is confusion among risk action owners about when to initiate risk responses, it suggests that the risk thresholds and triggers may not be well-defined or understood. Revisiting and clarifying these thresholds and triggers can help ensure that everyone involved understands the specific conditions under which a risk response should be initiated. This will reduce confusion and ensure that risk responses are executed consistently and appropriately.
PMI's risk management practices emphasize the importance of clearly defined risk thresholds and triggers to guide the timely and effective implementation of risk responses.
