Case Study on Software Cost Estimation Techniques

According to the survey, only one third projects overrun their budget and two thirds of all major projects overrun their original estimates. To make exact prediction of software development is a critical issue and it is difficult to determine how much effort a project and project managers to analyze it. It is little bit difficult to make the estimation about the project and determine how much time and manpower a project requires in the beginning. System analysts are unable to make realistic hardware- software during the system design phase and software project personnel cannot exactly tell their proposed budget. So, it is optimistic related to software development and also it is inevitable because it compromises as a consequence. But in fact huge overruns results from inaccurate estimates that are believed to occur frequently. The entire process of developing a cost for software is not different from any other element of cost. However, aspects of the process are peculiar to software estimating. Some of the unique aspects are driven by the nature of software as a product. Other problems are created by the nature of the estimating methodologies.
