It is one thing to talk about, anticipate, and/or resist change. It is another to make things happen. Depending on the size and impact of what is changing, you may need a formal project management plan to make sure that the changes are implemented well and that they stick. For smaller changes, you will still need a way to help the employees move into the new zone, ensure that things are working, confirm that people are adapting, and then evaluate what went well and what did not.
