This book introduces the concept of Performance Intelligence (PI). Centralized command and control methods that had worked in hierarchical organizations no longer can be effective in today’s service economy. The need to be responsive to evolving customer needs and desires creates organizational structures where business intelligence (BI) and decision making is pushed out to operating units that are closest to the markets. Closed-loop decision making resulting from combination of on-going performance management with on-going BI can lead to an effective responsive enterprise; hence, the need for performance intelligence (PI).
