Harry M. Sneed has a Master’s Degree in Information Sciences from the University of Maryland, 1969. He has been working in the IT field since 1967 when he started as a FORTRAN programmer for the US Navy Department. He migrated to Germany in 1971 and worked first for the Federal University Administration and then for Siemens in the database area. In 1978 he set up the first commercial software test laboratory in Budapest. There he developed the first German requirements engineering tool SoftSpec in 1982. That tool was used to document the requirements in many large German organizations, including BMW, Bertelsmann, Thyssen Steel and the German Railways. That tool was used not only to collect and store the requirements on the mainframe, but also to check the completeness and consistency of the requirements, as well as to generate a system design.

At the end of the 1980’s Sneed moved over to the field of reverse and reengineering and became involved in projects throughout Europe. In 2009 he received the Stevens Award from the IEEE Computer Society for his pioneering achievements in that field. He conducts courses at two technical colleges and two universities. He has published over 400 technical articles and written 23 books on the subjects of software testing, maintenance, migration and measurement. His work in requirement engineering is mainly in connection with reverse engineering, change management and test, three areas in which he still works as freelance consultant.
