This document discusses community driven innovation and how organizations can leverage external communities. It begins by introducing Red Hat's model of participating in open source communities to develop products in a cost effective manner. It then presents a community innovation pyramid with four levels: 1) listen to customers, 2) listen to the community, 3) innovate through the community, and 4) innovate within the community. The rest of the document provides advice on how organizations can operate at each level of the pyramid, including how to build and engage external communities, integrate community input, and adapt internal processes to support shared innovation.
