In a statement announcing Daichendt’s exit, Owen said the two had found they had divergent management styles and that our business views differ. Daichendt was accompanied in his departure from the Brampton, Ontario-based company by CTO Gary Kunis, who like Daichendt was previously at Cisco Systems and followed him to Nortel.

There was much speculation, when Daichendt and Kunis joined Nortel, that they would bring some hard-edged Cisco nous to a company just then emerging from a scandal in which it had to restate its financial reports and engaged in litigation against former senior officers. Evidently their style of running a company and developing, acquiring and marketing technology did not appeal to Owens.
