Both promoters and skeptics of the corporate social responsibility movement ought to turn to Michael E. Porter and Mark R. Kramer's essay in the December issue of the Harvard Business Review. The Harvard professors propose a way of thinking about the subject that goes beyond proactive or defensive do-goodism, which are useful as far as they go but make it hard to figure out what a company should do. Instead, the authors recommend a focus on a small number of initiatives with large and simultaneous benefits to the society and the bottom line -- Toyota's development of the Prius, for example, or Marriott's work in educating and training inner-city youths who come to work at its hotels. The goal, they argue, ought to be corporate social integration, not corporate social responsibility. Also worth looking at is a companion piece on nonprofit organizations that have a big impact by offering "good enough" solutions to social problems that succeed because they are simpler, cheaper and easier to deliver. Think mini-health clinics in drugstores and AP classes for rural high schools delivered over the Internet.
