COCOMO is a model designed by Barry W. Boehm to give an estimate of the number of man month it will take to develop a software product.
This "COnstructive COst MOdel" is based on a study of about 60 projects at TRW, which is a company where many large software projects are being build. The programmes examined where ranging in size from 2000 to 100.000 lines of code, and programming languages used range from assembly to PL/I.
Cocomo consists of a hierarchy of 3 increasingly detailed and accurate forms.
- Basic Cocomo - is a static single-valued model that computes software development effort (and cost) as a function of program size expressed in estimated lines of code.
- Intermediate Cocomo - computes software development effort as function of program size and a set of "cost drivers" that include subjective assessment of product, hardware,personnel, and project attributes.
- Advanced Cocomo - incorporates all characteristics of the intermediate version with an assessment of the cost driver's impact on each step (analysis, design, etc.) of the software engineering process.
