In January of 2007, as Home Depot shareholders seethed, Bob Nardelli took a $210 million exit package and resigned as CEO. This week, he landed the CEO job at Chrysler. \nThe troubled carmaker is newly private -- investment firm Cerberus announced in May it would buy Chrysler -- so Nardelli doesn't have to contend with angry (public) shareholders anymore. \nBut some of his less savory career milestones are being scrutinized this week. He came up through GE\u2019s fabled management ranks, only to get passed over for the top slot when Jack Welch retired in 2001.Reading the writing on the wall, he left GE in 2000, before Welch did, and hopped over to lead Home Depot, only to see its stock drop to $39.70 per share when he left -- down 10% from the $44.22 it traded at when he started.\nWhatever Nardelli does and doesn\u2019t accomplish at Chrysler, he\u2019ll be one of the most watched CEOs alive. Rightly so. He\u2019s got a reputation as a chief who knows I.T., having pushed Home Depot\u2019s controversial move into self-checkout technology and hired Bob DeRodes as Home Depot CIO to impose order -- namely, metrics -- on the technology team there.\nInformation technology may or may not help Chrysler now. The company\u2019s problems mainly stem from pension demand from retirees, health care costs and expensive unionized labor, according to CNNMoney. \nMeanwhile, Toyota earlier this year became the biggest car company on the planet, in terms of sales, in part thanks to smart, effective application of information technology. Barbra Cooper, CIO of Toyota, will be inducted into our Hall of Fame in October.\nI\u2019m wondering how long Sue Unger, longtime CIO of Chrysler, will work under Nardelli. Unger has created Chrysler\u2019s \u201cdigital factory\u201d for building virtual assembly lines and testing new-car design ideas. She\u2019s also known for innovation in both I.T. and finance, winning the Automotive Hall of Fame\u2019s Distinguished Service Citation last year.\nAlex Taylor, who has covered the car industry for years for Fortune magazine, thinks Nardelli is the wrong guy for the job, on Monday writing that Nardelli: \n\n"\u2026arrives on the heels of an enormous fiasco at Home Depot, appears to have a very high psychic profile, and by all accounts has the tact of a Marine drill instructor. This is not precisely what Chrysler needs at this point..." \nTaylor says Chrysler would do better to find a leader without Nardelli\u2019s \u201chard-charging\u201d and \u201caggressive\u201d style.On Chrysler's corporate blog,\nVP of communications, Jason Vines, defended Nardelli:\u00a0\n"A fresh set of eyes from outside the industry can find new and better ways of doing things. Our owners at Cerberus think Bob\u2019s incredible track record in successfully running the many businesses he did, at General Electric and on the retail side of Home Depot, can speed up the recovery of The New Chrysler. Everyone\u2019s future at Chrysler\u2014our employees, our dealers, our retirees, our supplier partners\u2014rests on a sustainable recovery. We know that."\n\nWell, we know it, too, and we'll be watching.\nUPDATE: Unger won\u2019t work under Nardelli at all, opting instead to remain on the Daimler side, as senior vice president and CIO for the German company, a spokeswoman for Unger says. Jan Bertsch, who reported to Unger and ran Chrysler\u2019s IT group, specifically, before Cerberus\u2019 buyout of Chrysler, will now become The New Chrysler\u2019s CIO.
