For example, Charlotte-based Wachovia ($666 billion in assets), which turned to IBM for help designing an SOA for its payments business, dramatically decreased the amount of time required for testing new products, according to An. Prior to the re-architecture, the bank faced obstacles in its testing because of rigid interfaces between its payments channels, he relates. "Now they can test just once," An says.
As a result of its SOA implementation, Wachovia has seen a 50 percent reduction in terms of time to market, as well as cost reduction when modifying, upgrading or adding a new payments interface, An says. This kind of speed and savings is increasingly important in the payments space as the business becomes more and more commoditized, he notes.
