A model-driven measurement procedure for sizing web applications: Design, automation and validation

Abstract:

This paper introduces the Object-Oriented Hypermedia Function Points (OO-HFP), which is a functional size measurement procedure for Web projects developed using the Object-Oriented Hypermedia (OO-H) method. This method provides model-driven and transformation-based support for the development of Web applications. Using OO-HFP, a size measure is obtained once a Web application's conceptual model is completed. We follow the steps of a process model for software measurement in order to detail the design and automation of OO-HFP. Finally, we present the validation of OO-HFP for Web effort estimation by comparing the pbkp_rediction accuracy that it provides to the accuracy provided by another set of validated size measures (the Tukutuku measures) that was found to be a good effort pbkp_redictor. The results of a study using industrial data show that the effort estimates obtained for projects that are sized using OO-HFP were similar to those using the Tukutuku measures, thus suggesting that the OO-HFP is a suitable effort pbkp_redictor. © Springer-Verlag Berlin Heidelberg 2007.
