George Koelsch is a system engineer who resides in Northern Virginia within the DC metro area. He started writing requirements 40 years ago while in the US Army, and has continued that work for the last 30 years as a contractor for the Federal Government. He became an efficiency expert during a five year stint as an Industrial Engineer at Michelin Tire Corporation, and he then applied that new skill to system engineering to tailor the lifecycle development process. He was among the first requirement engineers in the DC area to employ such a technique. Koelsch has authored ten non-fiction articles on computers, coin collecting, stamp collecting, and high-energy physics. He recently decided to combine his two passions, system engineering and writing.
