Everything about Barry Boehm totally explained
Barry W. Boehm is known for his many contributions to software engineering.
He was the first to identify software as the primary expense of future computer systems, he developed
COCOMO, the
spiral model,
wideband delphi, and many more contributions through his involvement in industry and academia.
In an important report to
DARPA (year?), Boehm predicted that software costs would overwhelm hardware costs. DARPA had expected him to predict that hardware would remain the biggest problem, encouraging them to invest in even larger computers. The report inspired a change of direction in computing.
Software economics
Barry Boehm's book
Software Engineering Economics (Englewood Cliffs, NJ : Prentice-Hall,
1981 ISBN 0-13-822122-7) documents his Constructive Cost Model (
COCOMO). It relates software development effort for a program, in man-years T, to
source lines of code (SLOC).
For a single software developer, k can be factored out by using more than 1 SLOC data point. In this case, x can be a fraction like 0.1 or 0.25.
- Note: since man-years are not interchangeable with years, Brooks' Law applies:
- Adding programmers to a late project makes it later.
- Thus this formula is best applied to stable software development teams which have completed multiple projects.
Spiral model
Boehm also created the
spiral model of software development, in which the phases of development are repeatedly revisited. This iterative
software development process influenced
MBASE and
extreme programming.
Wideband Delphi
Boehm refined the
Delphi method of estimation to include more group iteration, making it more suitable for certain classes of problems, such as software development. This variant is called the
Wideband Delphi method.
Education
Dr. Boehm received his
B.A. (1957) degree from
Harvard University, and his
M.S. (1961) and
Ph.D. (1964) degrees from
UCLA in 1961 and 1964, all in
Mathematics.
Career
Boehm has worked as educator and researcher for many years.
Boehm worked at
RAND,
TRW Inc.,
DARPA, and is currently TRW Professor of Software Engineering, Computer Science Department, and Director,
USC Center for Systems and Software Engineering (formerly Center for Software Engineering).
Awards
Recent awards include the Office of the Secretary of Defense Award for Excellence (1992), the
ASQC Lifetime Achievement Award (1994), and the
ACM Distinguished Research Award in Software Engineering (1997). He is an
AIAA Fellow, an ACM Fellow, an
IEEE Fellow, and a member of the
National Academy of Engineering. He received the Mellon Award for Excellence in Mentoring
(External Link
) on Tuesday, April 19, 2005.
