Detroit - CIO Magazine selected OnStar by General Motors the winner of the 2006 Annual CIO Grand Enterprise Value Award last night at the magazine's CIO|06: Year Ahead Conference in Phoenix, Ariz. The Grand Enterprise Value Award is the magazine's most prestigious award, and is recognized as one of the leading awards in the IT industry.

"Over the many years we've been doing these awards, it's become apparent that at successful organizations, IT is an integral part of the business," says Abbie Lundberg, editor in chief, CIO magazine.

"GM's OnStar was the judges' unanimous choice for this year's Grand CIO Enterprise Value Award because it delivers on so many critical dimensions: significant value to customers and the business; technical excellence behind the scenes with an extremely user-friendly front end; the social value of increasing the safety and security of drivers; and the continuous feedback loop of incorporating data from vehicle diagnostics into new car design. GM just seems to keep finding new ways to extract value from this system."

OnStar also won an Enterprise Value Award for the Manufacturing category and was one of twelve category winners being considered for the Grand Award. The Enterprise Value Award underscores the collaboration between information technology (IT) and business management and is bestowed upon a select group of organizations that clearly demonstrate how they leverage IT to achieve business objectives and positive business results.

"We are honored to have received the Grand Enterprise Value Award," said Chet Huber, president of OnStar. "Our entire team is focused on subscriber's services that are relevant and provide added peace of mind and we sincerely appreciate CIO magazine's recognition of our total organizational efforts".

OnStar reciently launched a new " Only GM" service called OnStar Vehicle Diagnostics where your car automatically performs hundreds of diagnostic checks on four key vehicle operating systems - the engine/transmission, anti-lock brakes, airbag and OnStar. The vehicle is automatically programmed to send the results via e-mail to the owner each month. This new service is another example of how OnStar continually strives to increase its relevance and value to its customers. Additionally, OnStar Vehicle Diagnostics is exclusively for GM customers, who have a 2004 model year or newer vehicle, and enhances GM's commitment to its Total Value Promise.

"OnStar is an industry-leading product differentiator for our company," said Ralph Szygenda, group vice president and CIO, General Motors. "OnStar leverages a number of technologies, but the fundamental relationship between IT and its business operations is the key ingredient to its success. We are gratified by CIO magazine's recognition of our achievements."

About the CIO Enterprise Value Awards
Enterprise Value Award entries are subjected to a rigorous judging process. Following a call for entries, applications were collected in the spring of 2005. CIO editors and a review board of independent consultants and academics examined the nominations and spoke with representatives of the various companies to evaluate their systems' costs and returns and impact on each company's overall operations. The team then presented their findings to a distinguished panel of judges, made up of prominent CIOs, for further evaluation. From there, the group selected 11 winning applications and 2 honorable mentions. After concluding site visits at the winning companies, the review board presented detailed findings of their research to the judges at a day-long meeting. Finally, judges determined one Grand CIO Enterprise Value Award winner, after debating the merits of each system, which will be announced at the CIO|06: The Year Ahead Conference in November 2005.
