Abstract:
Software effort estimation is essential for the project planning. Use case is widely used to capture and describe the requirements of customers and used as an index of software measurement and estimation. Based on the framework of traditional use case point estimation model, the paper presents UCSE, an effort estimation model based on use case specification. Firstly, the model abstracts factors influencing software effort from the use case specification and calculates the Use Case Weight, which is a kind of measurement of use cases size. Secondly, a function is constructed to translate the software size expressed by Use Case Weight to by software scale whose unit is kilo source line of code (KSLOC). Subsequently, effort estimation model COCOMO II is used to estimate the software effort according to the estimated software size measured by KSLOC. Compared with the traditional Use case point estimation model, UCSE model makes use of more relevant information and is more operable since i
t provides more concrete and objective references for the analysis and measurement of software effort factors in Use Case. What’s more, the presented case study shows its results are more stable.
