Appropriate resources contribute most to the effective implementation of risk responses. Resources include people, time, money, equipment, and materials that are needed to execute the risk responses. Without appropriate resources, the risk responses may not be implemented properly, timely, or efficiently, and may not achieve the desired outcomes. The other options are not as important as appropriate resources, as they are related to the understanding, comparison, or documentation of the risk responses, which are less critical than the execution of the riskresponses.
