It was nice knowing you, Malcolm Collins. Collins, who has headed Nortel's enterprise business since 2002, is leaving the company (was he pushed or did he jump?). His departure is part of a reorganization by Nortel to "better meet the needs of global enterprise and carrier customers in the converged marketplace" - whatever that means. Nortel will be split into two business units: the enterprise and packet networks division will be headed by Steve Slattery, while Richard Lowe, who was president of Nortel's CDMA business, will head up the mobiity and converged networks unit. So now that CEO Bill Owens has revamped the executive suites, how about articulating some strategic vision?
