The AARP is dedicated to making life better for people 50 and older, offering its 35 million members discounts on insurance, travel and more. Likewise, IT executives are dedicated to providing an application infrastructure of easily consumable Web services - for use by the business partners serving AARP members.

With Web services, AARP cuts the development time needed for point-to-point integration between its core membership back-end application and a business partner's front-end membership application from months to nil, says Brian Coyle, application architect at the Washington, D.C., nonprofit formerly known as the American Association of Retired Persons. AARP simply needs a couple of days to coordinate security and delivery of the Web services to the business partner. In turn, the business partner realizes a similar reduction in development time, he adds.

While Web services do let internal and external application developers work more efficiently, the bigger motivation is improved customer service for AARP’s members, Coyle says. That’s why the organization has embraced a service-oriented architecture (SOA) as the underpinning for its New Data Center-focused application development strategy.

“A services-oriented strategy lets AARP provide real-time membership data to business partners so they can provide the best possible customer service to members,” Coyle says.

AARP embarked on its services-oriented strategy three years ago as it planned how best to integrate a new third-party call center with its core membership back-end application, called Konnex. Running on a mainframe, Konnex handles all membership functions — dues processing, account updates, contact management and the like. It acts as the central rules repository to which all business partner membership applications interface.

Previously, the interaction between a third-party call center and Konnex would have taken place via batch processes or through an AARP-developed client/server application that the call center would then host. But with batch processes came overhead costs associated with transferring and loading files and the need to create comprehensive exception processes, Coyle says. “And using AARP-developed applications forced business partners to use multiple front-end applications to service members,” he adds.
