Case Studies in Object-Oriented Analysis and Design (Bk/Disk)

EDWARD YOURDON is an independent management consultant, author, and the widely-known developer of the 'Yourdon Method' of structured systems analysis and design. He is the author of over 100 technical articles. Currently, Mr. Yourdon is the publisher of the newsletter The American Programmer and speaks regularly at major computer conferences around the world. CARL A. ARGILA, PH.D., an independent software engineering consultant with more than 30 years' experience, offers training and consulting services in the areas of software systems analysis and design, software development methodologies, software project management, and the application CASE technology. Dr. Argila's major project involvements have included the Apollo project, The No. 1 ESS Electronic Switching System, the Trident Submarine, the B-2 Aircraft, and others.
