As a student, Nina worked in Warfield's Center for Interactive Management at University of Virginia. In 1980-1981 she was a programmer writing ISM software. She wrote this letter to Rose Warfield about 5 years later, after she had moved to University of Maryland for doctoral studies. Martin Marietta was a government contractor, an aerospace company where Nina worked after graduating with her Master's from University of Virginia, which is why she was in Denver and happened to meet Lonnie Fouty, the former Battelle employee. Through channels such as this Warfield sometimes discovered that information and use of ISM had been spreading and was being used with workable results, all unbeknownst to him. It was encouraging, but also frustrating. He would have loved to know much more about who was using ISM and what results were obtained. Unfortunately, private companies usually shielded their research and development from publicity because of business competition. This was one of a collection of correspondence shipped to GMU in April 2013.
