Technology companies can only compete by adding good management knowledge to their excellent technology knowledge, says a professor emeritus of business and electrical engineering at UC Davis. According to the Bureau of Labor Statistics, one of two engineers will become managers within the first 10 years of their professional employment. But Richard C. Dorf of the Graduate School of Management and the electrical and computer engineering department says many promoted for their excellent technical skills are often ill-prepared for the demands of management. Dorf addresses the need for encyclopedic management knowledge with a new 1,500-page book, "The Technology Management Handbook." As editor-in-chief, he compiled 220 articles to provide guidance for managers of technology or technology companies on business topics from fostering innovation to dealing with currency problems in international business. He is the author of more than 20 other books on technology and management and consults with technology firms in the West. Dorf says more technological entrepreneurs would be successful if they gave more attention and expertise to the management of their business. "It's an industry everybody wants to be in, but they don't realize it's not just technology that makes it. "The success of those enterprises is equally decided by management strategies and skills. They have technological solutions, but they must be commercialized," says Dorf. "That's what great business is about."
