Research and Application of Value Adjustment Factor Based on IFPUG Function Point Analysis Method
Lihua Fan · Journal of Qinghai Normal University · 2011
Currently,there are a great deal of methods in software size measurement,however,the most widely used method is FPA(Functional Point Analysis) of IFPUG(International Function Point Users Group),which is briefly introduced and the focus of study by this paper.Even though it has a wide application,the FPA has some disadvantages in the process of being used when calculating the VAF(Value Adjustment Factor) of software project.To make an improvement to the disadvantages,this paper aims to make an analysis and tries to overcome them by improving FPA method.The results showed that the improved method the paper is discussing based on the FPA method in estimating the software size is more closely functional on the factual development of the situation.
