Often sharing is used for low probability and low impact risk events regardless of the positive or negative effects the risk event may bring the project. Acceptance response is a part of Risk Response planning process. Acceptance response delineates that the project plan will not be changed to deal with the risk. Management may develop a contingency plan if the risk does occur. Acceptance response to a risk event is a strategy that can be used for risks that pose either threats or opportunities.
