Stephen Elop, Nokia

I ignored Yale management professor Jeff Sonnenfeld last year when he urged me to put Elop on the list.

Elop had only been on the job about a year – not enough time to give him a fair evaluation. Furthermore, I believe he’s got the unenviable task of running a business that, once the one to never count out, looks broken beyond repair. The ultimate measure, its stock, is trading near 15-year lows as the company, like Research in Motion, battles an industry that was upended by Apple’s iPhone and Google’s Android. Securing Elop’s name on this year’s Worst CEO candidates list: Nokia’s Easter Day launch of its long-awaited Windows-based phone. Easter. Really?
