Identifying Quality Attributes of FODA and DSSA Methods in Domain Analysis using a Case Study

The concept of reuse is addressed in software product line engineering (SPLE) by distinguishing between two types of processes for development: application and domain engineering. In domain engineering (DE), the focus is to define and manage all the valid combinations of reusable artefacts participating in the product line (PL) and the relationships between them. Domain analysis (DA) is the activity in DE, which describes the variability and commonalities in a domain. Instead of being applicable to a single software system, DA is applicable to multiple related software systems. Each DA method supports different quality attributes which are preserved while reuse. In this paper, two DA methods namely domain specific software architecture (DSSA) ad feature oriented domain analysis (FODA) are explained to model common and variable requirements of PL(s). A case study on Automated Teller Machine (ATM) is discussed using these two methods to identify quality attributes supported by these methods. This paper also discuss two different DA methods, which allows reusability for the identification, organization and knowledge modelling regarding the domain solution, so as to provide reuse among each element of domain.
