Towards Constructive Cost Analysis for demand based Reusable Domain Specific Components

Abstract

The prevailing software development methodology embraced by a majority of organisations is characterised by its agility. The neglect of normal analysis and design procedures is a consequence of the significant pressures associated with designing a product within specified time and budget constraints. This phenomenon could potentially result in a death of software of superior quality, while simultaneously impeding the constructive reuse of components. In the majority of component approaches, the demand of domain specific sofwatre components occurs during the later stages. In this paper, various components can be identified as demand based reusbale domain specific software components, which might also help in reusing these components in the subsequent increments. The strategy for extraction of components & procedure for reusing the existing components is described and a sample case to realize the same is presented.Still there is a dire need to early identify the demand based domain specific sofwatre components and perform the constructive cost analysis for the reusable domain specific software components. The issues related to the estimation of cost reuse measures are still challenging. This paper presents the constructuve cost analysis for the demand based reusable domain specific sofwtare components and proposes reuse measures for the family of applications with the quantized values. By analyzing these cost measures, the budget and effort in the development can be reduced. The results are estimated from the HR Portal domain specific softwrae application as a case study and its respective scenario has been explored in a better manner.
