ODR, Inc.

ODR, one of many consulting firms pitching its change management wares on the Web, has some interesting offerings scattered about their site. Check out, for instance, their "Challenge of Change" survey. It's a well-designed questionnaire on the scale and scope of changes being undertaken by organizations throughout the world. Fill it out online and they promise to send you a summary of the survey results. Or check out "Research" (under "What We Do") for the Databytes and ODR Research News newsletter. These sporadically produced publications include concise overviews of key areas of change management, examples of ODR's work, and examinations of the causes, responses and implications of change in specific industries.
