AN INTRODUCTION TO THE GOAL-DRIVEN IT ARCHITECTURE FOR AN AGILE ENTERPRISE
Well-organized business process models produce the actual value of the enterprise and puts it into the hands of customers.
But these process models are not sufficient to respond intelligently to changes, as their activities are not aware of "timely" changes on goals (vision, strategies, tactics).
Services that trace business processes at the IT system level need to be reconfigured according to service levels expected from these capabilities. They also need to be orchestrated by high-level goals to allow the resulting IT systems architecture to be aligned swiftly and coherently to changes.
By the use of business capabilities ( “what" the organization does ) instead of business processes ("how" the organization executes its capabilities), the focus is on the stability of how you operate.
With strategies and tactics that are realized by these processes, the focus is on measuring dynamic results of these processes and providing the capacity to evolve your decisions as quickly as possible in order to fine-tune these results to your changing environment.
The Business Motivation Model Diagram (BMM) referenced in the figure below shows how business processes realize strategies and tactics being guided by business rules.
As shown in the figure, business goals as part of the ends drive courses of actions (strategies and tactics), directives (rules and policies) till business processes.
