In Memoriam: James E. Long, Chief Methodologist
Jim Long spent most of his nearly 50-year career on the forefront of what is now known as systems engineering. An innovator, Jim created the industry’s first behavior diagram in 1967, which was, at that time, called a function sequence diagram. Jim’s career included a variety of technical, management, and executive positions with General Motors, TRW, and TITAN Systems, with many of his advances published in numerous conferences and trade journals. His work played a critical role in the development of aerospace, propulsion, defense, surveillance, and communication systems. A highly respected systems engineer, Jim is one of the world’s 35 named International Council on Systems Engineering (INCOSE) Fellows.
Jim co-founded Vitech and dedicated the final 18 years of his career as an energetic and passionate champion for model-based systems engineering and CORE, a model-based, integrated systems engineering software tool that connects people, processes, data, and documentation. He directed the development of Vitech’s systems engineering methodology and helped make Vitech a technical leader, advancing systems engineering as an industry and profession.
A member of INCOSE since 1992, Jim served the Council in many roles, including Corporate Advisory Board representative and president of the Washington Metropolitan Area Chapter, the largest chapter of INCOSE, and was a key contributor to numerous technical initiatives. In late 2010 the INCOSE Foundation established the James E. Long Memorial Post Doctoral Fellowship to honor and recognize his many contributions to the industry.
