By John S. McClenahen National Association of Manufacturers (NAM) President and CEO Jerry J. Jasinowski will step down in the fall of 2004 in what the business group describes as a "planned retirement." Jasinowski, who previously directed research and legislative activities for Congress' Joint Economic Committee and served as an assistant secretary of commerce during the Carter Administration, will have served in the top NAM job for 12 years. Heidrick & Struggles, an executive recruitment firm, will conduct a national search for a successor, reviewing both "external and internal" candidates, says Archie Dunham, chairman of ConocoPhillips, the third largest U.S. energy company and, until this week, the chairman of NAM. NAM is generally considered to be one of the four most powerful business organizations in Washington, D.C. The others are the U.S. Chamber of Commerce, the Business Roundtable and the National Federation of Independent Business.
