One Bank's SOA: Much More Than a 'Fire-and-Forget' Business Case

SOA offers a range of benefits, from costs savings to business agility. While the business agility aspect is difficult to measure and track, there are clearly advantages to be gained not only in efficiencies, but also faster time to market.

I recently had the opportunity to speak with Stan Limerick, director of technology strategy and architecture for Whitney National Bank in New Orleans, who described how his bank is attaining measurable results on a number of fronts. The key to Whitney's success is close collaboration with the business, he says.

Whitney began its SOA journey in earnest about a year and a half ago, when Limerick sought to address the multiple interfaces and legacy systems, some supported on a mainframe, and representing a range of messaging styles and interfaces. "We had everything from screen-scraping or sockets, you name it. This was our chance to standardize on something, and do it in the same style and form across the bank both for internal applications, as well as ASPs and business process outsourcers."

The scope of the integration was driven by the business units. "It was a highly involved process," Limerick says. "We had a fairly good functional taxonomy of the entire bank. It gave us a good way of lining up requirements for doing product selection and evaluation. The business themselves did the functional scoring, not IT."


The SOA effort was not presented to the business as "SOA," Limerick explains. "We explained to the business that their way of integrating and providing data, as well as integrating applications, is actually hindering them in several ways. If they wanted to go in and change suppliers, it was a significant effort, because they had all point-to-point interfaces, and we had to figure out what all would be impacted by that change. If we could get that decoupled, then they would have a lot more leeway in moving to better suppliers to give them competitive edge in market changes."


The SOA-based infrastructure enables business users to more easily swap out suppliers as needs change. "It gave the business guys a lot more leeway than what they would before," Limerick says. "It helped us on introducing new products, because its a much simpler environment." Limerick says the bank currently has less than a third of the interfaces it once had -- numbering more than 850. "This means that I can actually make changes and improvements in the environment much faster than I could before."


The new SOA-aware core banking application was built on IBM's WebSphere Process Server, IBM WebSphere DataPower appliances, and WebSphere Service Registry and Repository.


To track the progress of the implementation, Limerick meets every month with the bank's financial managers. "We go through all of the cost-savings aspects of the original business case. To see how were tracking to that. This wasn't a fire-and-forget business case. We're actually tracking month to month, to see if we are realizing the savings and benefits that we expected to see. And so far we slightly exceeded what we had in the business case."


These savings and benefits come from two areas -- cost savings within the technology group, and through operational efficiencies outside of the technology group. "It was based on process efficiencies and staff reductions across the bank, and we built the business case on a percent reduction base versus non-interest income."


While Limerick's team was able to build a strong business case on cost savings and efficiencies, they did not extend that to revenue-generation capabilities, at least not for now. "The business case stood on its own without that, so there was no reason to go there. Those numbers are always going to get pulled into question. We decided it wasn't even necessary, so let's not go there. We were able to give the on-the-line banker a lot more information about their customers, and things like that."


In this blog (formerly known as "SOA in Action"), Joe McKendrick examines how BPM and related business and IT approaches can promote business transformation.
