What best defines unplanned change?

Unplanned change is characterized by its unexpected nature and the lack of preparation that accompanies it. This type of change occurs spontaneously and is often triggered by unforeseen circumstances or events, which can disrupt the norm and require immediate adaptation. For instance, natural disasters, sudden market shifts, or unanticipated policy changes exemplify unplanned change, as they are not initiated by deliberation or strategic planning.

In contrast, the other options describe various forms of change that involve intention and preparation. Deliberate decision-making, as mentioned in the first choice, suggests a thorough process where change is carefully considered and planned out. The second option focuses on change that is approached with prior knowledge and readiness, indicating that stakeholders are aware of and prepared for the change. Lastly, the notion of temporary duration relates to change that may be short-lived, rather than focusing on the unexpected nature of unplanned change. Defining change by its permanence rather than its preparation further differentiates it from the essence of unplanned change.
