WHY CONSIDER A GOAL-DRIVEN ALIGNMENT FOR YOUR IT ?
AN INTRODUCTION TO THE GOAL-DRIVEN IT ARCHITECTURE FOR AN AGILE ENTERPRISE
Abstract
Well-organized business process models produce the actual value of the enterprise and puts it into the hands of customers. They permit to standardize work for large numbers of people doing repetitive work, but not fine-tune the results of minute-to-minute decision-making.
Alone, these processes are not enough to respond intelligently to emerging risks and opportunities because their activities are not aware from changing strategies and tactics. Business Processes and SOA Services that trace them at the IT system level, both need to be controlled by business strategies and tactics. Integrating the latter as an orchestrator for business capabilities permits to the resulting Goal-Driven IT systems Architecture to be aligned swiftly and coherently on the changing business strategies and tactics.
With business capabilities ( “what" the organization does ) and 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 the dynamic results of these processes and on the capacity to evolve your decisions as quickly as possible in order to fine-tune and adapt 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 (strategy and tactic), directives (rules and policies) till business processes.
