Because Microsoft technology uses Web services, XML, and Service Oriented Architectures (SOAs), Microsoft and partner applications can be tightly integrated to provide a strong, yet flexible multichannel delivery system. For banks, that means that a standardized infrastructure can be employed simply and cost-effectively. Microsoft technologies are designed to integrate with existing bank systems and generate new value from them, not replace them.
"In an industry that spends 8 percent of revenue on IT—the highest amount of any industry group—Microsoft's capability to integrate is significant," says Warren Lewis, bank industry marketing director at Microsoft. "That's especially true because banks are under increasing pressure to reduce costs and get more value from their current systems."

A standardized infrastructure based on Microsoft technology can help banks improve the customer, employee, and operations experience while building capacity for continued innovation. Because the Microsoft technology platform is designed for easy integration, banks can rapidly implement new solutions as needed to meet their changing business needs.
The goal: Affordable banking solutions with lasting value. As Lewis explains, "In the old days when banks built a new system, they locked it down for years. Today, the industry needs what we call sustainable transformation. This really means built for change." Lewis continues, "Change has to be an integral part of the design. That's a key element of a standardized infrastructure that uses industry standards and Web services."
