Software effort estimation at early stages of project development holds great significance for the industry to meet the competitive demands of today’s world. Accuracy, reliability and precision in the estimates of effort are quite desirable. The inherent imprecision present in the inputs of the algorithmic models like Constructive Cost Model (COCOMO) yields imprecision in the output, resulting ...

One of the major activities in effective and efficient production of software projects is the precise estimation of software development effort. Estimation of the effort in primary steps of software development is one of the most important challenges in managing software projects. Some reasons for these challenges such as: discordant software projects, the complexity of the manufacturing proces...

We can say a software project is successful when it is delivered on time, within the budget and maintaining the required quality. However, nowadays software cost estimation is a critical issue for the advance software industry. As the modern software’s behaves dynamically so estimation of the effort and cost is significantly difficult. Since last 30 years, more than 20 models are already develo...

There are numerous forecast models of software development costs, however, various problems become apparent in context to practical application. Standardized methods, such as COCOMO II have to be calibrated at an individual operational level on the basis of the underlying database. This paper presents a new activity based approach that is based on business specific cost data that can be easily ...

Software cost estimation is an important phase in software development. It predicts the amount of effort and development time required to build a software system. It is one of the most critical tasks and an accurate estimate provides a strong base to the development procedure. There are many cost estimation models for the estimation of the software. COCOMO model is the basic model. In this pape...

Intermediate COCOMO Model computes effort as a function of program size and a set of cost drivers. Effort adjustment factor (EAF) is calculated using 15 cost drivers. EAF is an important significant factor in computing software development effort. We have taken one delivered development project of size of 479 function points and planned for 917 Person days of SEI CMM Level 5 “Excellent” Company...

1. Software Project Cost Estimation The development and use of effective and efficient methods for estimating the costs of software development remain difficult challenges in software engineering. Many studies have shown wide discrepancies between estimates and actual costs and completion schedules of software development (e.g., [Vijayakumar 19971). Project managers strive to make accurate esti...

Software Cost Estimation is the challenging factor in project management. Accurate cost estimation helps to complete project with in time and budget. Due to this behavior of the project it is considered as a risky project .Under these conditions risk management is mandatory. Large numbers of estimation models have been proposed over the last 30 years. Constructive Cost Model (COCOMO) is one of ...

Estimation of a software project failure is based on project analogies in the area of software cost estimation. In all software cost estimation approaches important decisions must be made regarding certain approaches in order to obtain reliable estimate. A reliable and accurate estimate can be proved by simulation approach. A simulation modeling approach is proposed for the prediction of softwa...
