Harvard Business School’s recent curriculum development sounds most promising (“Field of Dreams,” December 3, 2011). Already famous for the case method, which has been used in business education across the globe for decades, HBS is now trying something completely different: learning by doing. As you report, fieldwork is the rage. And all this comes from Nitin Nohria, who became HBS’s dean only last year. Although the practical addition to the curriculum has an awkward name, Field Immersion Experiences for Leadership Development or FIELD, it is based on an idea that promises to spread even farther afield than the case method. The very best in business are the proof, for most of them have learned by doing rather than by going to some school. Oops. Sorry about this. But I am sure HBS’s staff will get around this little glitch in no time. They must be learning by doing, too.
