The objective is to manage the change in requirement specifically in global software development in an appropriate manner. The proposed frame-work RCM_GSD follows the required processes of RCM and reduces the concerns of GSD. Systematic Literature Review (SLR) was conducted for exploration of relevant research. During literature study, it is analyzed that the existing techniques of change management were not suitable for global software development (GSD). The change in requirements becomes more complicated in distributed environment due to the lack of communication and collaboration among globally dispersed stakeholders. The proposed model is compared with other models proposed in recent literature and analysis is made between them;feedback was obtained from the domain experts as well. The feedback and comparison results show that the proposed model provides an appropriate solution for requirement change management in GSD.展开更多

From last decade, researchers and practitioners are trying to establish successful transfer of practices of formal methods into industrial process development. In the last couple of years, numerous analysis approaches and formal methods have been applied in different settings to improve software quality. In today’s highly competitive software development industry, companies are striving to deliver fast with low cost and improve quality solutions and agile methodologies have proved their efficiency in acquiring these. Here, we will present an integration of formal methods, specifications and verification practices in the most renowned process development methodology of agile i.e. extreme programming with a conceptual solution. That leads towards the development of a complete formalized XP process in future. This will help the practitioners to understand the effectiveness of formal methods using in agile methods that can be helpful in utilizing the benefits of formal methods in industry.展开更多

The benefits include faults found in earlier stage of software development, automating, checking the certain properties and minimizing rework. In spite of their recognition in academic world and these claimed advantages, formal methods are still not widely used by commercial software industry. The purpose of this research is to promote formal methods for commercial software industry. In this paper we have identified issues in use of formal methods for commercial applications and devised strategies to overcome these difficulties which will provide motivations to use formal methods for commercial applications.展开更多

UML diagrams are useful to show an interaction, behavior and structure of the system. Similarly, in requirement engineering, formal specification methods are also being used in crucial systems where precise information is required. It is necessary to integrate System Models with such formal methods to overcome the requirements errors i.e. contradiction, ambiguities, vagueness, incompleteness and mixed values of abstraction. Our objective is to integrate the Formal Specification Language (Z) with UML Sequence diagram, as sequence diagram is an interaction diagram which shows the interaction and proper sequence of components (Methods, procedures etc.) of the system. In this paper, we focus on components of UML Sequence diagram and then implement these components in formal specification language Z. And the results of this research papers are complete integrated components of Sequence diagram with Z schemas, which are verified by using tools and model based testing technique of Formal Specifications. Results can be more improved by integrating remaining components of Sequence and other UML diagrams into Formal Specification Language.展开更多
