Has Nortel's outgoing CEO Bill Owens set the stage for Mike Zafirovski to become a hero (and become quite wealthy in the process)? Nortel's third-quarter results show across-the-board strength, highlighted by strong wireless sales. Could this suggest Nortel is poised for a rebound now its accounting and financial troubles have mostly been addressed? Before anyone gets too carried away with a single quarter's performance, take a deep breath, step back and get a lay of the telecom landscape. Nortel still has huge challenges ahead, ranging from unfocused R&D to competition from low-cost suppliers to outstanding class-action lawsuits and a $1.275 billion debt refinancing in February. Zafirovski, who was cleared to become CEO earlier this week after he agreed to give back a $11.5 million to his former employer, Motorola, has already hinted there are more cost reductions on the way. It could be that Mike Z. will be able to pull off another turnaround story but it is going to be a huge uphill journey for a company that still has  all kinds challenges/problems. It appears, by the way, that Mike Z. is already onboard unofficially given he participated in today's analyst call where he outlined his six priorities, which include a "clear strategic focus" and "profitable growth". Another thing Mike Z. may want to focus on is not getting into money-losing contracts just to penetrate a new market. The $500-million wireless deal Nortel signed with BSNL has led to losses of nearly $300-million. In hindsight, this deal could be Bill Owens' biggest strategic mistake, while only time will tell if the acquisition of PEC and the joint venture in South Korea work out.
