The blog listed below posted a good list of steps to take when leading change.
Here was my response to their post. I appreciate the steps you’ve outlined for successful change management. In my own experience, I find that all the steps are important. I would add one additional step. The leaders must understand the impact that their behavior has on the project. (I call this Level 3 support or resistance.) I have seen otherwise brilliant ideas and plans die, simply because the leaders caused so much fear and mistrust that people’s attention (and energy) went into worrying, avoiding, and sometimes sabotaging the project just to save themselves. Little is written about the critical role of the behavior of leaders on change, but their words, actions, reactions, and so forth, can make or break projects.
