For almost twenty years, I, and many colleagues, have been working with managers and teams in developing enhanced learning capabilities: systems thinking, improving mental models, fostering dialogue, nurturing personal vision, and building shared visions. For the last four years, a group of us at MIT have begun to develop a consortium of corporations to advance the theory and method underlying this work and to demonstrate what is possible when organizations "get serious" and when people work together over years to integrate new learning capabilities into important work settings. This consortium, the MIT Center for Organizational Learning, now involves about twenty corporations, mostly Fortune 100 firms.
