Abstract

Researches on software development process suitable for small size software organizations tend to the combination of CMMI and Agile methodology. Among them the combination of CMMI and Scrum has the most popularity. Research how we combine XP, one of main development model of agile methodology, with CMMI is still a challenge problem. In this paper, we identify performers in each practice areas and each practices when applying CMMI to small size software organizations which are experienced to XP methodology. We apply our solution to two IT organizations and compare the result with our previous work. Eventually we confirm that our novel solution needs less period of achievement of CMMI level 4.
