Integrating RUP Approach with Agile Method for Large Scale Projects

Nagy Ramadan Darwish, Ahmed Ali Mohamed Warad


Software has become part of all aspects of our lives, and organizations are increasingly conceiving extremely large and complex software projects. Software industry has an option to choose suitable methodology/process model for its current needs to provide solutions to give problems. According to some researchers, a hybrid approach can help optimize the software development lifecycle by combining two or more methodologies. eXtreme programming (XP) and Scrum are most widely practiced and documented agile models. Both XP and scrum work well for small projects whereas Rational Unified Process (RUP) is suitable for large projects. This paper analyzes characteristics, strengths, and weaknesses of both conventional and agile methods. This paper also explains the four major phases and nine disciplines of the RUP, XP and the common elements of the Scrum process. Finally, this paper suggests a new hybrid software development method that combines the RUP with XP and Scrum process to accommodate the strengths of both methods while suppressing their weaknesses to get high quality and improve the team productivity. The  hybrid  method  can  be  utilized  in  the  software industry, particularly, in the  business  sectors  that deal with large-scale projects.
