Biography
Yourdon obtained his
In 1964 Yourdon started working at
In June 1997, Yourdon was inducted into the Computer Hall of Fame, along with such notables as Charles Babbage, James Martin, Grace Hopper, and Gerald Weinberg.[2] In December 1999 Crosstalk: The Journal of Defense Software Engineering named him one of the ten most influential people in the software field.[3]
In the late 1990s, Yourdon became the center of controversy over his beliefs that Y2K-related computer problems could result in severe software failures that would culminate in widespread social collapse.[4] Due to the efforts of Yourdon and thousands of dedicated technologists, developers and project managers, these potential critical system failure points were successfully remediated, thus avoiding the problems Yourdon and others identified early enough to make a difference.[5]
In the new millennium, Yourdon became Faculty Fellow at the Information Systems Research Center of the University of North Texas as well as Fellow of the Business Technology Trends Council for the Cutter Consortium, where he also was editor of the Cutter IT Journal.[6]
Work
After developing
Yourdon Inc.
In 1974, Yourdon founded the consulting firm Yourdon Inc. in New York, which provided consulting, educational and publishing in the field of software engineering. In the early 1980s, the company had multiple offices in North America and Europe and a staff of 150 people. They trained over 250,000 people in the topics of structured programming, structured design, structured analysis, logical data modeling and project management.[1]
In 1986, Yourdon sold the consulting company. It later became part of the Canadian (Québec) software company CGI Informatique. The publishing division had published over 150 books on software engineering topics before it became part of Prentice Hall.[1]
Yourdon structured method
In the 1980s Yourdon developed the Yourdon structured method (YSM) in
- The behavioral model: states that system behavior can be described in three ways: functions, dynamics and relationships.
- The processor environment model (PEM): describes the allocation of computing functions in processor hardware.
- The software environment model (SEM): defines the software architecture and its effects from each processor.
- The code organizational model (COM): shows the modular structure of each task
The Yourdon structured method (YSM) and
Year 2000 (Y2K) problem
During the late 1990s, he was one of the leading proponents of the theory that the '
Final years and death
In his final years, Yourdon served as an internationally recognized expert witness and computer consultant specializing in project management, software engineering methodologies, and Web 2.0 development. He died on January 20, 2016, as a result of a post-surgical blood infection.[10]
Personal life
Yourdon was married to Toni Nash. He had three children; daughter Jennifer, and sons Jamie and David. He also had five grandchildren; Liam Christopher, Owen Edward, Edward Roland ("Teddy"), Elliot ("Ellie") Ann, and Khalil Slice. Yourdon had five sisters; Toni, Teri, Tina, Aleda, and Patrice.
Yourdon was also an avid photographer whose photos were published in
