Porter and Kramer suggest a new approach to CSR which both (i) acknowledges the interdependence of companies and the broader community, and (ii) enables companies to develop a tailored, rather than generic, CSR strategy.

This note provides a summary of Porter and Kramer's article, giving particular attention to the practical issues of creating a tailored corporate social agenda.
