Abstract
Software cost estimation plays a vital role in software project management. It is a process of predicting the effort and cost in terms of money and staff required for developing the software system. It is very much clear that software project will be successful if its estimated cost will be near to the real cost. When the project is at the acquisition stage the least details are available about a software project to be developed, due to which Problems arises in cost estimation. As the stages move on details increases for software development of software which is quite fruitful in cost estimating. However, it can be considered that estimating the software cost in the first phases will produce better results. In this research cost estimation techniques are discussed along with the issues in that particular technique and focus will be on understating the points or issues which cause hurdles or issues in estimating the cost of the software project.
Highlights
Estimating the software cost is very important but it is difficult to do so as well
This study will help the researchers as well as practitioners for selecting suitable software cost estimation model. For this systematic literature study article is divided into multiple sections which are as:
Software cost estimation is essential to the contract, negotiating with the client and writing for the request of the proposal, Monitoring and controlling
Summary
Estimating the software cost is very important but it is difficult to do so as well. In the early era of software development, there were very fewer instructions in software, as the software size is increased the accuracy in the cost of estimation increased. Nowadays large software projects increased up to 25 million lines of source code [1]. A huge amount of large software systems could not meet the deadlines, runs over budget or face cancellation of the project due to underestimation or overestimation of software cost at the phase of requirement engineering. In this study different software cost estimation techniques proposed and finding their issues with the help of systematically selecting the researching databases, selecting article and deciding their selection or rejection criteria. This study will help the researchers as well as practitioners for selecting suitable software cost estimation model. For this systematic literature study article is divided into multiple sections which are as: Methodology for literature study
