Which of the following is NOT a characteristic of an Emergency change?

An emergency change is characterized by the need for swift implementation due to an urgent situation, such as a major incident or security breach. The goal is to minimize the impact on the business or ensure service continuity. Typically, emergency changes are implemented as quickly as possible, which aligns with the first option; they often address critical issues, which supports the third option; and they often require a post-implementation authorization process from the Change Advisory Board (CAB), as indicated by the second option.

Option D, which suggests that an emergency change has a predefined extensive approval process, is not characteristic of an emergency change. This is because the very nature of an emergency change is to bypass some of the slower, more methodical approval processes that are typically in place for regular changes. The urgency of the situation calls for immediate action rather than a lengthy approval procedure, which is why this option stands out as incorrect in describing an emergency change.
