Effort Measures

By effort in the software estimation process, we mean the amount of person-effort, or labor, that will be needed to carry out a task. It can be measured in any units, as long as the unit is kept consistent. On the other hand, the de facto standard is staff-hours (person-hours),

The Steps in Estimating
The Steps in Estimating

Generally, the steps in the software effort and cost estimation process are shown in “The SEI CMM and Estimating” Figure (b). We'll look at these next.

COCOMO : A Regression Model
COCOMO : A Regression Model

The COnstructive COst MOdel (COCOMO) is perhaps the most extensively used estimating technique. It is a regression-based model developed by Dr. Barry W. Boehm when he was at TRW in the early 1970s. He began by analyzing 63 software projects of various types. The
