Accurate cost estimation helps to complete project within time and budget. Many estimation models have been proposed over the last 30 years. This paper provides a detail overview of existing software cost estimation models and techniques. Cost estimation models are basically of two types: algorithmic and non-algorithmic. It also includes the recent developed techniques for software cost estimat...

The literature review shows software development projects often neither meet time deadlines, nor run within the allocated budgets. One common reason can be the inaccurate cost estimation process, although several approaches have been proposed in this field. Recent research studies suggest that in order to increase the accuracy of this process, estimation models have to be revised. The Construct...

In the dynamic software field there are major challenges in adapting metrics and cost estimation methods to continuing changes. There is a need to assess emerging trends and re-interpret software size measures and estimation models for new processes. Future trends of software systems are overviewed with implications for software sizing and cost estimation capabilities. Methods are shown to hand...

––Software development cost estimation is important for effective project management. Many models have been introduced to predict software development cost. In this paper, a novel emotional COnstructive Cost MOdel II (COCOMO II) has been proposed for software cost estimation. In COCOMO II only the project characteristics are considered, whereas the characteristics of team members are also impor...

Software project management is one of the significant activates in the software development process. Software Development Effort Estimation (SDEE) is a challenging task in the software project management. SDEE is an old activity in computer industry from 1940s and has been reviewed several times. A SDEE model is appropriate if it provides the accuracy and confidence simultaneously before softwa...

Software development has become an important activity for many modern organizations (Pressman, 1997). In fact the quality, cost, and timeliness of developed software are often crucial determinants of an organization’s success. There are significant financial and strategic implications for development projects in terms of activity scheduling and cost estimation. Software cost estimation is one o...

Software cost and effort estimation is the most vulnerable issue in software development technology. Due continuous changing resources and customer involvements, software effort estimation has become more challenging issue in software management. To accurately estimate software cost and effort is difficult for both developers as well as customers. It has become very difficult to establish relat...

Reliable effort estimation remains an ongoing challenge to software engineers. Accurate effort estimation is the state of art of software engineering, effort estimation of software is the preliminary phase. The relationship between the client and the business enterprise begins with the estimation of the software. Accurate effort estimation gives a good cost estimate.The authors have proposed an...

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...

Estimating the costs of software development is one of the most important activities in software project management. Inaccuracies in such estimates may cause irreparable loss. A low estimate of the cost of projects will result in failure on delivery on time and indicates the inefficiency of the software development team. On the other hand, high estimates of resources and costs for a project wil...
