C code for Intermediate Cocomo Model

The constructive cost model was developed by Barry W. Boehm in the late s [1] and published in Boehm’s book Software Engineering Economics [2] as a model for estimating effort, cost, and schedule for software projects.

These projects were based on the waterfall model of software development which was the prevalent software development process in The need for the new model came as software development technology moved from mainframe and overnight batch processing to desktop development, code reusability, and the use of off-the-shelf software components.

The first level, Basic COCOMO is good for quick, early, rough order of magnitude estimates of software costs, but its accuracy is limited due to its lack of factors to account for difference in project attributes Cost Drivers.

The constants a bb bc b and modwl b are given in the following table note: However it does not account for differences in hardware constraints, intermediae quality and experience, use of modern tools and techniques, and so on.

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.

This extension considers a set of four “cost drivers”, each with a number of subsidiary attributes: Each of the 15 attributes receives a rating on a six-point scale that ranges from “very low” to “extra high” in importance or value.

An moddl multiplier from the table below applies to the rating. The product of all effort multipliers results in an effort adjustment factor EAF. Typical values for EAF range from 0.

The coefficient a i and the exponent b i are given in the next table. Detailed COCOMO incorporates all characteristics of the intermediate version with an assessment of the cost driver’s impact on each step analysis, design, etc.

The detailed model uses different effort multipliers intermediatee each cost driver attribute. These Phase Sensitive effort multipliers are each to determine the amount of effort required to complete each phase.

COCOMO – Wikipedia

In detailed cocomo, the whole software is divided into different modules and then we apply COCOMO in different modules to estimate effort and then sum the effort. The effort is calculated as a function of program size and a set of cost drivers are given according to each phase of the software life cycle. From Wikipedia, the free encyclopedia.
