It ignores requirements, customer skills, and hardware issues.

Provide ideas about historical projects.

Easy to implement with various factors.

Easy to estimate the total cost of the project.

Advantages and Disadvantages of COCOMO ModelДЇollowing are some advantages and disadvantages of the COCOMO model.

#Cocomo model and its variations software

It is the advanced model that estimates the software development effort like Intermediate COCOMO in each stage of the software development life cycle process. Given the estimated size of the project is: 300 KLOCДeveloper having highly application experience: 0.82 (as per above table)Дeveloper having very low experience in programming: 1.14(as per above table)Д®ffort (E) = a*(KLOC) b *EAF = 3.0*(300) 1.12 *0.9348 = 1668.07 MM Calculate the Effort, Scheduled time for development by considering developer having high application experience and very low experience in programming.

COST DRIVERS PARAMETERSД®xample :В For a given project was estimated with a size of 300 KLOC.

#Cocomo model and its variations driver

a, b, c, d = The constant parameters for the software project.Д®AF = It is an Effort Adjustment Factor, which is calculated by multiplying the parameter values of different cost driver parameters.

KLOC = The size of the code for the project in Kilo lines of code.

The estimated effort and scheduled time are given by the relationship: The intermediate model estimates software development effort in terms of size of the program and other related cost drivers parameters (product parameter, hardware parameter, resource parameter, and project parameter) of the project. Also, calculate the Average resource size and Productivity of the software for Organic project type.ДЄns :В Given estimated size of project is: 300 KLOC For OrganicД®ffort (E) = a*(KLOC) b = 2.4*(300) 1.05В =В 957.61 MM Calculate the Effort, Scheduled time for development.

a, b, c, d = The constant parameters for a software project.Д®xample : For a given project was estimated with a size of 300 KLOC.

KLOC = the size of the code for the project in Kilo lines of code.

D = Total time required for project development in Months (M).

E = Total effort required for the project in Man-Months (MM).

The estimated effort and scheduled time for the project are given by the relation:

It mainly deals with the number of lines of code and the level of estimation accuracy is less as we donвЂ™t consider the all parameters belongs to the project. In addition, the MSCM model provides some insights about thГЁ behavior of software development processes and environment, which could be used to formulate guidelines for better software project management polices and practices.It is the one type of static model to estimates software development effort quickly and roughly. Judged by both criteria, the MSCM model is comparable to, if not better than, the SLIM, and significantly better than the rest of the modeis.

The MSCM model is compared with other widely used software cost models, such as COCOMO and SLIM, on the basis of goodness of fit and quality of estimation using software project data sets available in the literature. Specifically, we prГ©sent the Minimum Software Cost Model (MSCM), derived from economic production theory and Systems optimization. Software development could be modeled as an economic production process and we therefore propose a theoretical approach to software cost modeling. One of the major difficulties in Controlling software development project cost overruns and schedule delays has been developing practical and accurate software cost models.
