People are only human, and as a change manager or change agent, it is important to keep that in mind. Reactions can and will vary depending on the person and the presented CHANGE.
Here are three basic change concepts that can be use to help better understand and assist others through change.
Avoid Change - "What ever it is, I don't want it!" If this person can be convinced, they can be your strongest change advocate. If not, they may tear down any progress. Identify these persons as soon as possible; try to remember, you may not be able to convince everyone.
Change Ahead - "Bring it on!" Leverage their enthusiasm!
Right Behind You - "Tell me what you need me to do." Takes little convincing and feeds on ques from others.
More Details - "Show me the fine print." Sometime may seem to challenge the change. Provide a sound case and the details. Logic can bring these folks around.
What Change? - "What! I didn't know about that." Either change neutral or strongly reacts when surprised. Keep them informed and they're likely to join the journey.
