| '''Barry W. Boehm''' (born 1935) is an American [[software engineer]], TRW Emeritus Professor of Software Engineering at the Computer Science Department of the [[University of Southern California]], and known for his many contributions to [[software engineering]].
| |
| | |
| == Biography ==
| |
| Boehm received a [[Bachelor of Arts|B.A.]] in [[mathematics]] from [[Harvard University]] in 1957, and a [[Master of Science|M.S.]] in 1961, and [[Ph.D.]] from [[UCLA]] in 1964, both in [[mathematics]] as well.<ref name="Boe97">[http://sunset.usc.edu/Research_Group/barry.html Barry Boehm] TRW Professor of Software Engineering, Computer Science Department Director, USC Center for Software Engineering. Accessdate 2008-10-18.</ref>
| |
| | |
| In 1955 he started working as a Programmer-Analyst at [[General Dynamics]]. In 1959 he switched to the [[RAND Corporation]] where he was Head of the Information Sciences Department until 1973. From 1973 to 1989 he was Chief Scientist of the Defense Systems Group at [[TRW Inc.]]. From 1989 to 1992 he served within the U.S. Department of Defense (DoD) as Director of the [[DARPA]] Information Science and Technology Office, and as Director of the DDR&E Software and Computer Technology Office.<ref name="Boe97"/> Since 1992 he is TRW Professor of Software Engineering, Computer Science Department, and Director, [[University of Southern California|USC]] Center for Systems and Software Engineering, formerly Center for Software Engineering.
| |
| | |
| He has served on the board of several scientific journals, including the IEEE Transactions on Software Engineering, Computer, IEEE Software, ACM Computing Reviews, Automated Software Engineering, Software Process, and Information and Software Technology.<ref name="Boe97"/>
| |
| | |
| Recent awards for Barry Boehm include the Office of the Secretary of Defense Award for Excellence in 1992, the [[American Society for Quality|ASQC]] Lifetime Achievement Award in 1994, the [[Association for Computing Machinery|ACM]] Distinguished Research Award in Software Engineering in 1997, and the [[IEEE]] International [[Stevens Award]]. 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 in 2005<ref>[http://www.usc.edu/programs/cet/mentoring/mellon/awards/ Mellon Award for Excellence in Mentoring on Tuesday, April 19, 2005.]</ref> and the IEEE Simon Ramo Medal in 2010.
| |
| | |
| == Work ==
| |
| Boehm's research interests include [[software development process]] modeling, software [[requirements engineering]], software [[architecture]]s, [[software metrics]] and cost models, [[software engineering]] environments, and knowledge-based software engineering.<ref name="Boe97"/>
| |
| | |
| His contributions to the field, according to Boehm (1997) himself, include "the Constructive Cost Model ([[COCOMO]]), the [[Spiral model|Spiral Model]] of the software process, the Theory W (win-win) approach to software management and requirements determination and two advanced software engineering environments: the TRW Software Productivity System and Quantum Leap Environment".<ref name="Boe97"/>

| | |
| === Software versus hardware costs ===
| |
| In an important 1973 report entitled "Ada - The Project : The DoD High Order Language Working Group" to the Defense Advanced Research Projects Agency ([[Defense Advanced Research Projects Agency|DARPA]]),<ref>William A. Whitaker (1993). [http://archive.adaic.com/pol-hist/history/holwg-93/holwg-93.htm Ada - The Project : The DoD High Order Language Working Group]. Accessdate 2008-08-06.</ref> 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 1981 book ''Software Engineering Economics'' documents his Constructive Cost Model ([[COCOMO II|COCOMO]]). It relates software development effort for a program, in man-years T, to ''source lines of code'' (SLOC).
| |
| | |
| <math> T = k * (SLOC)^{(1+x)}</math> | |
| | |
| 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, [[Frederick P. Brooks|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 ===
| |
| [[File:Spiral model (Boehm, 1988).png|thumb|160px|Spiral model (Boehm, 1988).]]
| |
| 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.
| |
| | |
| ===Incremental Commitment Model===
| |
| The Incremental Commitment Model (ICM) <ref>Brown, A.W., and Meyers, S. 2005. COINCOMO—Combining Elements of the COCOMO Suite, ISPA, June 2005. To be available through http://sunset.usc.edu/cse/pub/publication/techReport.html</ref> is a system design, developmental, and evolution process for the 21st Century systems. The systems' types cover a wide range from COTS based systems to "routine" Information Systems to human intensive and life or safety critical.<ref name="ReferenceA">Boehm, B., Brown, A. W., and Koolmanojwong, S. Demonstration Proposal: Incremental Commitment Model for Software. University of Southern California, Los Angeles, CA. 90089.</ref>
| |
| It was only in 1998, after the development of the ICM that Barry Boehm along with A Winsor Brown started to focus on reconciling it with the [[WinWin]] [[Spiral Model]] and its incarnation in [[MBASE]] <ref>Boehm, B., Abts, C., Brown, A. W., Chulani, S., Clark, B. K., Horowitz, K., Madachy, R., Reifer, D., and Steece, B. 2000. Software Cost Estimation with COCOMO II. ISBN 0-13-026692-2. Prentice Hall PTR Upper Saddle River, NJ.</ref> and the follow-on [[Lean MBASE]],<ref>Boehm, B. 2005. Guidelines for Lean Model-Based (System) Architecting and Software Engineering – Version 1.5. University of Southern California, Los Angeles, CA. 90089. http://greenbay.usc.edu/csci577/spring2006/site/guidelines/index.html.</ref> and working towards an Incremental Commitment Model for Software (ICMS) by adapting the existing [[WinWin]] [[Spiral Model]] support tools.<ref name="ReferenceA"/>
| |
| In 2008, the evolving ICM for Software with its risk-driven anchor point decisions, proved very useful to several projects which ended up having unusual life cycle phase sequences.<ref name="ReferenceA"/>
