Relationships are important and there is a lot of trust and respect among the people. It goes back to relationships and safety. If people have real relationships, they can have fun working together even when a project is not going so well or times are tough. The biggest mistake is that the highest leadership isn't committed to the change. The senior leaders have to believe that it is the direction they want to go.
Organizations often tend to take on too much at once.
If the organization is working on other major initiatives, they could be working at cross-purposes. It's really important to be sure that a change effort will dovetail with other initiatives so people are not being pulled in two different directions. Another pitfall is not supplying enough information about the changes. People are reluctant to change when they don't understand all the reasons for it. Reducing the fear, anxiety and resistance to change has a lot to do with education.
