Robert Kegan and Lisa Lahey at Harvard’s Graduate School for Education have developed potent learning tools to help leaders shift from old behaviors and step into new ones. Most of my work with leaders incorporates at least a few of these tools, in particular their Immunity to Change Map. This map is designed to articulate a primary ‘learning edge’ for an individual as well as the undermining patterns, fears and beliefs—their immunity to change--that hold them back from growth and evolution.
Kegan and Lahey share their extensive organizational development research in several publications including An Everyone Culture: Becoming A Deliberately Developmental Organization and Immunity to Change: How to Overcome It and Unlock the Potential in Yourself and Your Organization.
For a good summary of their approach and its impacts, see this overview about their work from Harvard’s website.
