George Koelsch was a systems engineer who retired to West Virginia. He started writing requirements 47 years ago while in the US Army and had continued that work for his last 33 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 metro area to employ such a technique. Koelsch has authored more than ten non-fiction articles on computers, coin collecting, stamp collecting, and high-energy physics. This is the second time he has combined his two passions, system engineering and writing.
