This is a complex market. You can buy from brokers ortweeners or vendors. Or eBay. There are license transfers,inspection fees and third-party maintenance options. There'sdisposition to think about. (How do you throw this stuffout without running afoul of the Environmental ProtectionAgency?) Just learning the lingo is a chore. But as CIOs ofenterprises both large and small are currently learning, therewards for diving into the secondary market can be great.

Here, then, is CIO's tour of the secondary market - its characters, itscharacteristics, the products and the prices that areinsane!

The Buyers - Why the CEO Loves Bill Haser

Bill Haser might be bragging a little bit, but he has a right to. "Intwo years, we've driven out about a quarter of our operational costs,"says the CIO of Tenneco Automotive, a $3.5 billion auto partsmanufacturer in Lake Forest, Ill. "I told a CIO about that, and hethought I was joking. I'm not. The savings have been very substantial,and the chairman has recognized us for it. A large part of thatsavings has been leveraging the secondary market."

Haser is in a minority and a majority here. He's in a minority becausehe is one of only a few CIOs willing to speak on the record about thesecondary market. Either through some sort of hand-me-down shame ormaybe to protect relationships with vendors, many CIOs aren't.
