For the school that so boldly launched the MBA 100 years ago and went on to become the bluest of blue-chip brands in business education, it seemed only fitting that Harvard Business School should mark its centennial year by examining the future of the degree it invented. "It was our view that you need to think critically about what you are doing every 100 years or so, whether you need to or not," Dean Jay Light wryly observed in opening remarks to an unprecedented campus gathering last March of business school deans, corporate recruiters, and executives. It was a welcome moment of levity given the seriousness of the topic at hand. Some of the schools represented had already implemented major MBA program reforms. Others were considering them. But everyone had one thing in common: Each had assisted HBS professors Srikant Datar and David Garvin in their painstaking research to render the most complete contemporary picture of MBA education.
