Download Toyota's Legacy System Renewal Model

Following this approach, Toyota Motor Sales USA gains flexible legacy systems at far less cost than outright replacement.

At times like these, taking on the high risk and cost to replace or rewrite 15- and 20-year-old systems is unpalatable. But so is doing nothing to alleviate the performance and profit drain. Karen Nocket, divisional information officer, Automotive Systems, Toyota Motor Sales USA and a 2009 CIO Ones to Watch winner, developed a renewal model for legacy systems that includes complexity reduction, data consolidation, report deletion and cleanup, and batch cycle reduction and documentation. The results are legacy systems that are more scalable and flexible at a lower cost than outright replacement. It's possible to renew even the dinosaurs of IT—mainframes.

"Our mind-set has really changed over the past couple of years on the value of the mainframe," says Nocket. "In addition to improving the legacy systems to be more stable and scalable, we are also putting Web applications, services and complicated data analytics and reporting on the mainframe, and we're using it as a very big, secured server."

Toyota's approach has three steps: 1) assessment of the health of systems, support, documentation and plans; 2) achieving readiness by defining needed flexibility and measuring potential reduction of code and process complexity and 3) renewal of the systems and the resources around them.
