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. Reifer, and Bert Steece. International symposium on Empirical Software….

We are tring to provide a common plateform to the students and professionals to share their knowledge among others because knowledge is the only thing that increase when it is shared. Not worth serious attention”. Nature Inspired Coop-erative Strategies for Optimization.

COCOMO – Wikipedia

The cost drivers are grouped into four categories: Limitations Its accuracy is necessarily limited because of its lack of modep which have a significant influence on software costs The Basic COCOMO estimates are within a factor of 1. The detailed model uses different effort multipliers for each cost driver attribute.

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.

This extension considers a set of four “cost drivers”, each with a number of subsidiary attributes: How do you determine which method is right? The effort intdrmediate calculated as a function of program size and a set of cost drivers are given according to each phase of the software life cycle. Topics Discussed in This Paper.

The rating uses a scale very low, low, nominal, high, very high, extra high which describes to what extends the cost driver applies to the project being estimated. How successful were they? Phase-sensitive Effort Multipliers The effort multipliers for every cost drivers are different during the software development phases Module-Subsystem-System Hierarchy The software product ontermediate estimated in the three level hierarchical decomposition.

The constructive cost model was developed by Barry W. This article needs additional citations for verification. These Phase Sensitive effort multipliers are each to determine the amount of effort required to complete each phase. Please help improve this article by adding citations to reliable sources.

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.

A lot of research work has been done for the correct and accurate use of effort estimation models. 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.

Cost drivers are used to adjust the nominal cost of the project to the actual project environment, hence increasing the accuracy of the estimate.

The product of all effort multipliers results in an effort adjustment factor EAF.
