In response to a number of major upheavals in the networking industry, Cisco Systems Inc. announced last month a restructuring of the company from its existing three lines of business to one core business with 11 business units. Under the old organizational structure, San Jose, Calif.-based Cisco had three specific lines of business: enterprise, service provider and commercial. According to Andrew Sage, director of marketing at Cisco Systems Canada Co. in Toronto, the need for separate lines of business no longer exists. Consolidation in the industry has blurred the lines and many products are no longer only used by one business category. "In a nutshell, what's happened is we've consolidated our development and marketing efforts," Sage said. Now product marketing and development are all under one organization.
