Edward Nash Yourdon April 30, — January 20, was an American software engineer , computer consultant , author and lecturer, and software engineering methodology pioneer.

Yourdon obtained his B. Later in the s and early s after working at a small consulting firm and as independent consultant, in Yourdon founded his own consulting firm, YOURDON Inc. In the late s, 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.

He is the author of the book Decline and Fall of the American Programmer. In , Yourdon founded the consulting firm Yourdon Inc. In the early s, the company had multiple offices in North America and Europe and a staff of people. They trained over , people in the topics of structured programming, structured design, structured analysis, logical data modeling and project management. In , Yourdon sold the consulting company. The publishing division had published over books on software engineering topics before it became part of Prentice Hall.

The method supports two distinct design phases: analysis and design. YSM includes three discrete steps: the feasibility study; essential modeling; and implementation modeling. During the late s, he was one of the leading proponents of the theory that the ' Y2K bug ' could lead to a collapse of civilization, or at least protracted economic depression and technological breakdown on a wide scale.

Yourdon was criticized by some when his predictions vigorously refuted by some experts in advance failed to materialize at the scale predicted. This may have caused him to lose credibility with some in the software industry. 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. He died on January 20, , as a result of a post-surgical blood infection.

Yourdon was married to Toni Nash. He had three children; daughter Jennifer, and sons Jamie and David. Yourdon authored over technical articles and authored or coauthored 26 computer books since A selection:.

This material was briefly covered during lectures on March 14, ; this page describes Coad and Yourdon's method - particularly, the design evaluation criteria it provides - in more detail than in the lecture. Coad and Yourdon's method for object-oriented design appeared shortly after their method for object-oriented analysis , and it seems clear that they're intended to be used together. This might possibly make their method easier to use than other current methods - but, on the other hand, it seems possible that it could also limit the types of systems to which it could be applied. This method is also discussed, more briefly, in recent editions of Pressman's Software Engineering: A Practitioner's Approach. Coad and Yourdon recommend use of the same set of layers for a design as they do for a class diagram in their object-oriented analysis:. Coad and Yourdon recommend the use of a CASE tool that would allow you to select which layers you wish to see, when viewing the model of the system that's being developed.

Object-oriented Analysis. Object-oriented analysis starts with a traditional structured specification, and adds the following information:. A list of all objects - A list describing the data contents of each noun , or physical entities in the DFD. A list all system behaviors - A list of all verbs within the process names such as Prepare order summary report, generate invoices, etc.
