For the rapid advances of Internet technologies in recent years, EB (Electronic Business) has gained many attentions as a major theme for enterprises to keep their competitiveness. Amongst all possible endeavors, research has shown that an effective management of business processes is a critical source for enterprises to achieve their EB goals. In this paper, we present a layered architecture that employs such well-known constructs as the social BPM (Business Process Management) lifecycle and the TOGAF (The Open Group Architecture Framework) framework to support an effective management of business processes where the use of social tools in the BPM lifecycle under the TOGAF framework is particularly emphasized. To illustrate, the architecture is applied to the social BPM of an enterprise for book publishing.
