These give a general impression of the software project.Īre relatively small, simple software projects in which small teams with good application experience work to a set of less than rigid requirements.Īre intermediate (in size and complexity) software project in which teams with mixed experience levels must meet a mix of rigid and less than rigid requirements.Īre software project that must be developed within a set of tight hardware, software, and operational constraints. We will go more into detail about these levels of Cocomo.Ĭocomo calculates Effort (E) and Development time (D) using kilo lines of code (KLOC).Ĭocomo may be applied to three classes of software projects. 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.įor this project we only implemented the Basic and the Intermediate versions. Is a static single-valued model that computes software development effort (and cost) as a function of program size expressed in estimated lines of codeĬomputes 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. The programms examened where ranging in size from 2000 to 100.000 lines of code, and programming languages used range from assebly to PL/I.Ĭocomo consists of a hierarchy of 3 increasingly detailed and accurate forms. 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. Boehm to give an estimate of the number of man month it will take to develop a software product.
