Barry Boehm

In 1996, Boehm was elected as a member into the National Academy of Engineering for contributions to computer and software architectures and to models of cost, quality, and risk for aerospace systems.

[5] In an important 1973 report entitled "Ada - The Project : The DoD High Order Language Working Group" to the Defense Advanced Research Projects Agency (DARPA),[9] 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.

[citation needed] Boehm's 1981 book Software Engineering Economics documents his Constructive Cost Model (COCOMO).

It relates software development effort for a program, in Person-Months (PM), to Thousand Source Lines of Code (KSLOC).

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.

[11] 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.
