Banks need a flexible architectural model for the growth of banking services – one that enhances interoperability and reduces integration costs. The BIAN model is a Service Oriented Architecture with consistent service definitions, level of detail and boundaries. This makes it easier to choose and integrate commercially available products of different vendors.
By working together through BIAN, we can reduce integration costs, align IT with business objectives and therefore respond quicker to customer needs. The result: it will be easier to seamlessly integrate package solutions info your existing landscape.
Why is SOA important?
BIAN and its members believe that SOA is the best technology for internal and external interfaces to produce consistent definitions, levels of detail and boundaries through collaboration. When combined with industry-agreed IT standards, SOA will ensure interoperability, whereby different IT systems within a bank can work together as seamlessly as possible, without additional time or cost requirements for integration.
The value proposition for SOA derives from:
- Agility — Improving the ability of the organization to make changes to systems, mostly by separating portions of the systems that can evolve independently.
- Asset leverage — Improving the use of assets reduces or eliminates the development and implementation of redundant business logic.
- Standardization and quality — Creating standardized services enables best practices to be replicated. It also increases the efficiency and facilitates the improvement of development processes.
