RISK
DEFINITIONS
LRO Accepted and Residual Risk Definitions
RISK: A risk is any potential set of circumstances that may affect mission
cost, schedule, technical performance or safety.
ACCEPTED RISK: A LRO “accepted risk” is defined as a risk that the
Project opts to accept on the basis of any of the criteria stated below:
–The risk has been mitigated to an acceptable level as deemed by
Project management (implies minimal impact to the Project if the
conditions occur).
–The cost/schedule/technical impact of further mitigation exceeds
the perceived value of the mitigation.
–The mechanisms for mitigating the risk lie outside of LRO control.
–No further mitigation options are available/viable for the risk.
*Note: An accepted risk may or may not be a residual risk, but continued efforts to
mitigate are not deemed practical.
RESIDUAL RISK: A LRO “residual risk” is any accepted risk with the
capacity to affect LRO’s ability to meet Level 1 Requirements (full mission
success criteria).
*Note: A residual risk must always be an accepted risk. Residual risks cannot be
further mitigated without undue impact to cost, schedule, or technical performance.
