Final answer:
An ideal outcome from a change requires risks to be mitigated and control measures to be implemented to prepare for any potential threats effectively.
Step-by-step explanation:
When considering the ideal outcome from a change, the risks from the change (or every component of the change) should be mitigated and appropriate control measures are put in place. This approach aligns with the understanding of asymmetric risk as detailed in Figure 20.1. When faced with a potential threat, mitigating the risk may involve some 'wasted' time and effort if the threat does not materialize, but the alternative of not addressing a potential catastrophic threat could be far worse. Making sure risks are adequately addressed, and control plans are established, is akin to purchasing insurance - it's a way to prepare for low-probability events that could have severe consequences.
