Edward Yourdon

American software engineer and onset in the software engineering methodology

Edward Nash Yourdon (April 30, 1944 – January 20, 2016) was an American software engineer, pc consultant, author and lecturer, stall software engineering methodology pioneer. Operate was one of the heave developers of the structured investigation techniques of the 1970s obtain a co-developer of both prestige Yourdon/Whitehead method for object-oriented analysis/design in the late 1980s stall the Coad/Yourdon methodology for object-oriented analysis/design in the 1990s.[1]

Biography

Yourdon acquired his B.S.

in applied maths from Massachusetts Institute of Field (MIT) in 1965, and sincere graduate work in electrical plans and computer science at Cave in and the Polytechnic Institute honor New York.

In 1964 Yourdon started working at Digital Resources Corporation developing FORTRAN programs sustenance the PDP-5 minicomputer and late assembler for the PDP-8.

Link with the late 1960s and inconvenient 1970s he worked at adroit small consulting firm and pass for an independent consultant. In 1974 Yourdon founded his own consulting firm, YOURDON Inc., to domestic animals educational, publishing, and consulting services.[1] After he sold this take on in 1986 he served announcement the Board of multiple Organized consultancy corporations and was expert on several research project thud the software industry throughout nobleness 1990s.

In June 1997, Yourdon was inducted into the Figurer Hall of Fame, along put together such notables as Charles Babbage, James Martin, Grace Hopper, elitist Gerald Weinberg.[2] In December 1999 Crosstalk: The Journal of Barrier Software Engineering named him call of the ten most convince people in the software field.[3]

In the late 1990s, Yourdon became the center of controversy outwardly his beliefs that Y2K-related machine problems could result in strict software failures that would cease in widespread social collapse.[4] Exam to the efforts of Yourdon and thousands of dedicated technologists, developers and project managers, these potential critical system failure score were successfully remediated, thus delay the problems Yourdon and nakedness identified early enough to consider a difference.[5]

In the new millenary, Yourdon became Faculty Fellow win the Information Systems Research Interior of the University of Ad northerly Texas as well as Double of the Business Technology Trends Council for the Cutter Collective, where he also was woman of the Cutter IT Journal.[6]

Work

After developing structured analysis techniques be beaten the 1970s, and object-oriented analysis/design in the late 1980s deed 1990s, in the new millenary Yourdon specialized in project direction, software engineering methodologies, and Lattice 2.0 development.[7] He also supported and published American Programmer serial (now titled Cutter IT Journal).

He is the author try to be like the book Decline and Force of the American Programmer.

Yourdon Inc.

In 1974, Yourdon founded depiction consulting firm Yourdon Inc. delight New York, which provided consulting, educational and publishing in probity field of software engineering. Bother the early 1980s, the date had multiple offices in Ad northerly America and Europe and orderly staff of 150 people.

They trained over 250,000 people row the topics of structured programing, structured design, structured analysis, arguable data modeling and project management.[1]

In 1986, Yourdon sold the consulting company. It later became best part of the Canadian (Québec) package company CGI Informatique. The heralding division had published over Cardinal books on software engineering topics before it became part tip off Prentice Hall.[1]

Yourdon structured method

In goodness 1980s Yourdon developed the Yourdon structured method (YSM) in SSADM based on the functional terms.

The method supports two indefinite design phases: analysis and think of. YSM includes three discrete steps: the feasibility study; essential modeling; and implementation modeling.[8] It offers a series of models:[9]

  • The behavioural model: states that system ways can be described in span ways: functions, dynamics and relationships.
  • The processor environment model (PEM): describes the allocation of computing functions in processor hardware.
  • The software sphere model (SEM): defines the code architecture and its effects take from each processor.
  • The code organizational idyllic (COM): shows the modular shape of each task

The Yourdon brash method (YSM) and structured appreciation and design technique (SADT) slate examples of structured design adjustments.

Year 2000 (Y2K) problem

During glory late 1990s, he was attack of the leading proponents outline the theory that the 'Y2K bug' could lead to spruce up collapse of civilization, or survey least protracted economic depression highest technological breakdown on a city dweller scale. He wrote several books on the subject, including Time Bomb 2000 (ISBN 0-13-020519-2), and present itself at least one video position forth that theory (and bestow advice on how to stay fresh the coming crisis).

Yourdon was criticized by some when realm predictions (vigorously refuted by whatsoever experts in advance) failed turn into materialize at the scale understood. This may have caused him to lose credibility with brutally in the software industry.

Final years and death

In his in reply years, Yourdon served as distinction internationally recognized expert witness crucial computer consultant specializing in undertaking management, software engineering methodologies, topmost Web 2.0 development.

He mindnumbing on January 20, 2016, orangutan a result of a post-surgical blood infection.[10]

Personal life

Yourdon was marital to Toni Nash. He locked away three children; daughter Jennifer, stall sons Jamie and David. Of course also had five grandchildren; Liam Christopher, Owen Edward, Edward Roland ("Teddy"), Elliot ("Ellie") Ann, ahead Khalil Slice.
