Abstract
In IT software and system development projects, two main streams of management methods can be found. One is traditional method, which is the Plan-driven, and the second one is Agile method. This paper reports a quantitative investigation result on where the Agile development method has been used, and on how it is related with project success. The statistical analysis with over 120 projects in Japan will reveal that the Agile development has been applied in the project situations where novelty on market, system complexity as well as likelihood on largescale rework should be all higher. Further, our findings suggest that the stakeholder satisfaction level would be higher in the Agile development projects.
