structured analysis and design technique based on the Yourdon/Demarco/Constantine Structured Analysis/Structured Design technique. Frick, while working with Case at Nastec Corporation on the development of the PC-based DesignAid product, was the first to specify and teach a comprehensive technique for transforming a structured analysis specification into a structured design. The professional services division quickly became not only the largest component of Nastec Corporation, but also the largest provider of SA/SD education. Case was among the most prolific public speakers on the subject of CASE during the 1980s, helping launch, among other events, the Computer-Aided Software Engineering Symposium as its keynote speaker for its first two years. Case toured the country, promoting the integration of upper CASE and lower CASE with pro-football great and code-generation pioneer Fran Tarkenton, founder of Tarkenton Software. When Tarkenton Software and Nastec Corporation agreed not to merge, Tarkenton teamed up with James Martin and merged Tarkenton Software into KnowledgeWare, a direct competitor to Nastec. Principles of Computer Aided Software Engineering Case, also author of the book Information Systems Development: Principles of Computer Aided Software Engineering (Prentice Hall, 1986), was also a lifelong student of general systems theory (GST) and fascinated by the application of structured analysis and design techniques to the design of entire business operations, not just the information technology subsystems. At Gartner, Case quickly ascended the analyst ranks, going from the leading Software Engineering analyst to head of its business process reengineering practice - where he could spend full-time applying GST to business design, launching Gartner's e-Business Resource Center, its Vertical Industries practices and ultimately becoming the founder, group vice president and general manager of Gartner's TCO Software division. From there, Case became head of Gartner's IT benchmarking business and president of Gartner's eMetrix business performance management business. During his 13-year tenure at Gartner, Case launched dozens of product and service lines that accounted for over $100 million in revenue to Gartner. Stamford Research He had a consulting firm Stamford Research, LLC, with Arnold Kwong and Steve Vogel.
