Nortel Networks Corp has instituted another round of cost-cutting and a structural re-organization that sees the elimination of the position of chief technology officer (CTO). Nortel says the moves reflect the growing impact of the "sustained and growing economic downturn" and end the tenure of John Roese, who was hired as Nortel's CTO in mid 2006 to coordinate and execute Nortel's overall R&D strategy (R$, July 7/06).
