I came across a useful diagram at work the other day while working on a big project at the largest hospital in our system. While working there we were up against a staff that was very change averse. An organizational psychologist was recommended by the administration team to talk with us regarding the hospitals work culture and we were given this diagram below to help us determine what our project was missing to get it on the right track.
The diagram shows high level pieces that need to be addressed in order to successfully help the person accept change. Following the flow diagram from left to right, change will not happen as desired if any piece is missing. The person going through change will then experience the far right outcome depending on the missing piece.
