Development Lifecyles for Web sites

Thomas J. McCabe Thomas J. McCabe, founder of McCabe & Associates in Columbia, Maryland, is internationally known for his development of software metrics and his leadership in developing methodology and automation that foster the continued improvement of quality in software development, testing and maintenance. In 1998 he sold his business to venture capitalists and made the transition from scientist to entrepreneur. In 1999 he was appointed to lead the Washington DC chapter of the Chief Executive Officers (CEO) Club, a group consisting of founders and entrepreneurs. Additionally he chairs a group of Mentors, this group consists of CEOs who have built, run and sold companies and are in pursuit of their next challenge. Tom also actively speaks across the country on software development as well as on entrepreneurship. His newly formed company is McCabe Technologies. Tom McCabe was the 1998 recipient of the fourth international Stevens Award and presented the Stevens Lecture on Software Development Methods on March 10th in Florence, Italy. He also testified before congress in the hearing entitled, “Year 2000: Biggest Problems and Proposed Solutions” in June of 1998. CNN Headline News aired a segment featuring Tom McCabe where he was interviewed on the Year 2000 in 1998. Tom McCabe’s landmark research appears in “Design Complexity Measurement and Testing” which was published in 1989 in Communications of the ACM. Other publications include “Software Complexity” with Arthur Watson, CrossTalk, 1994; “Combining Comprehension and Testing in Object-Oriented Development” with Arthur Watson, Object Magazine, 1994; “Testing an Object-Oriented Application” with Lori Dreyer, Albert Dunn, and Arthur Watson, The Journal of the Quality Assurance Institute, 1994; “An Engineering Approach of Software Maintenance” with Eldonna Williamson, CASE Outlook, 1992; Tips on Reengineering Redundant Software” with Eldonna Williamson, Datamation, 1992; and “Reverse Engineering, Reusability, Redundancy: The Connection”, American Programmer, 1990.
