There are obvious benefits in making business policies/rules explicit and easily changed via accompanying quick-change processes. The apparent benefits revolve around faster reaction to competitors and markets, as well as quick response to management and collaborative tuning. There are more subtle opportunities to get ahead of the game and anticipate customer demand, thus creating the ability to generate incremental revenue streams that play off of increased demands. Customers may also be enabled to make changes to their individual processes as they interact with an organization. CRM efforts are struggling to have a differentiating customer experience. BPM with explicit rules will allow this experience to evolve and become individualized.
Substitute a standard web services interface for a speaking tube, a business rules management system for his encyclopedic knowledge of policies and regulations, data mining or predictive analytics for his customer knowledge and adaptive control for his experimentation and you have Decision Management. The Answerer but on an industrial scale.
