Banking on SOA
At Wachovia Bank, Tony Bishop and his boss, CIO Susan Certoma, made a huge bet on SOA. Now, theyre on their way to completing the platform for innovation the company needed.
The surprising answer, supported strongly by her CEO: Rock the boat, change everything, and build a multihundred million dollar, end-to-end, services-oriented development and delivery platform, backed by a business-focused, product management culture in IT.
While many enterprises nibble at the edges of SOA, Wachovia’s CIB division opted for a ubiquitous services architecture to support the innovation and efficiency it needed to catch competitors (see also "Wachovia's Steps to SOA Success").
“This was a great opportunity for Wachovia,” Certoma says. “This is a very large business growing rapidly, but with not so much entrenched legacy that you couldn’t take a vision and platform to a whole new level.”
To help realize that vision, Certoma hired Tony Bishop as senior vice president and director of product management. Bishop already learned a lot building SOA platforms for financial services. “IT needs to be flexible, adaptable, scalable,” Bishop observes. “It can’t just be about modeling my business processes as a system. It has to be holistic.”
Eyeing the prize
Corporate and investment banking is a complex business. With dozens of highly customized
financial products and services ranging
from IPOs and derivatives to leasing, research, advice, and trading, each of the nine
business units within CIB demanded its
own unique applications, Certoma says. And all of their businesses are intensely
competitive, with extreme pressure to get
better products to market faster and at lower cost.
Furthermore, financial products require lots of data-intensive modeling, so there’s a premium on high performance applications that can give traders and analysts an edge. “It’s all about complexity,” Certoma says. “There’s a great deal of money to be made if you have the top talent and the technology to do it.”
The vision Certoma proposed in 2004 was a complete restructuring of how CIB did development, centered around a core of reusable frameworks, components, and services that each of the business units could leverage. Each business had been building similar capabilities over and over—desktop presentation, data management, workflow management, messaging, and customer information management. “If we did it right, it would give them a lift on productivity,” Certoma explains, “and over time it would be cheaper, because the output for our fixed cost would be multiples greater.”
Fast forward 20 months, and Certoma’s plan is bearing fruit. CIB’s Equity Structured Products unit, for example, needed a better “equity volitility” application, to analyze the financial risks of new derivatives products they were thinking of offering.
“A lot of them were modeling deals on Excel, and it would take anywhere from half an hour to a couple hours,” Certoma explains. Using CIB’s new “volatility surface capability” component—shared across CIB—plus new common desktop and server frameworks and a utility grid framework for performance, developers in the Structured Products group were able to build a highly customized, high performance app quickly.
“They put in all their parameters, and within less than a minute started to see all the trending along the screen, the different aspects of the deal like pricing and interest rate scenarios,” Certoma says. “It lets them be much more productive, and model more scenarios.”
Mapping to the business
To get the SOA ball rolling quickly, Certoma recruited 265 technologists with expertise in
SOA and building financial services
apps.
