Traditional project management methodology – being inflexible- was unable to respond to varied and continuous customer requests in a quick changing software development environment. In contrast, Agile project management methodology provides a set of methods that have been successfully applied to small and medium projects, but there is doubt as to the suitability of this approach to larger projects. Therefore , the main aim of this research is to conduct an identification and analysis of benefits obtained when Agile Project Management Methodology is applied in large software development projects. The study also strives to determine if agile methods work successfully on a large scale. Qualitative research was carried out as a multiple – case study. Primary data was collected through five semi-structural interviews to software professionals with huge experience and knowledge of agile methodologies. The main benefits obtained were visibility, Quality, employee and customer satisfaction. Moreover, this paper gives reasonable evidence that supports the success of agile project management methodology in large software projects.
