The document discusses integration strategies, contrasting traditional 'point to point' approaches with the enterprise service bus (ESB) model, highlighting the benefits of agility and efficiency. It emphasizes the importance of treating systems as reusable components and improving visibility through a centralized service repository. Additionally, it outlines the business advantages of implementing an ESB, including enhanced capital efficiency and faster revenue growth.

The difference in the ESB approach
Systems abstracted as services. Flexibly joined via their
business interfaces, regardless of protocol

Business agility through reuse
 Treat your new and existing systems as components
– Access these components through business interfaces
 Break down barriers between departments
– Stop re-inventing the wheel
– Stop exposing your internal organizational structure to your customers
– Build your integrations once
 Consider visibility of your services
– Use a central repository to share information about services
– Set standards for how to facilitate, monitor, and manage reuse

An ESB is the foundation for an agile business
 Consider the business tasks in a process
– Some involve people
– Some involve IT systems
 An ESB exposes the business
tasks that the systems perform,
via business interfaces
 The process layer does not need
to be aware of the systems
themselves, just the task
 The ESB does not need to be aware of the
business process
 Processes in different departments
reuse the same business tasks for
common process steps

An example – removing manual steps from business
processes
 Many business processes could be straight-through for the majority of cases
 Reaching this point is evolutionary
– What are the exceptions that require manual intervention?
– What are the business rules that identify those exceptions?
– What is the most efficient order to perform the tasks?
– How do we gain visibility into the process, without manual steps?
 An integration layer that exposes business services is key
– The process logic must be able to change rapidly
– Integration development should not be required to re-order a process
– The integration layer must support the visibility requirements of the business

Visibility
 Establishing an ESB is about more than simplifying integration
 It establishes a common pattern and framework for accessing services
–From business processes
–Between departments
–Between systems
 This common layer enables powerful visibility into the business

The power of Information
 The business value of the information flowing through an ESB is huge
–Identify business events immediately, as they occur
• Exploit new business opportunities
• Identify risks
–Do something before the opportunity is lost
• Contact your customers exactly
when they are ready to listen
• Prevent fraud
–Differentiate yourself
• Offer something your
competitors can’t
