For years, Epic Systems has been the "quiet, stalking giant" of health care IT, racking up more and more hospitals, medical groups and health systems as customers while carefully trying to stay out of the limelight as much as possible. So what's the secret to the success of this "quiet company"? HCI is working on an in-depth profile of what has become one of the most-remarked-on, yet perhaps still least-understood success stories in healthcare IT in the past decade. Are you a CIO or senior IT executive with Epic experiences? A consultant who has advised on an Epic implementation? An analyst who has studied the organization? If so, we'd like your input. Please e-mail HCI Editor-in-Chief Anthony Guerra. Your participation will help us paint the fullest portrait possible.
