Step-by-step explanation:
When the nurse manager identifies a key person on the organizational chart who will be affected by a change, it is important to pay attention to the people above and below this person on the organizational chart. This means considering the impact of the change on the entire chain of command, as well as any potential reactions or concerns from those who have authority over or are under the key person. By considering the broader context and relationships within the organization, the nurse manager can better navigate the change and ensure its success.
