Extreme programming:Reassessing the requirements management process for an offsite customer

Software engineering literature and practice have shown that efficient requirements management forms the essence of a successful software project. When the requirements are volatile and the development environment is unstable, Extreme Programming (XP) methodology provides efficient means to cope with requirements through the onsite customer practice. However, for many software companies, having an onsite customer present is difficult to achieve. To solve this problem an Offsite Customer Process Model has been proposed earlier. This paper reports results from a study of a mobile application development project where the model was empirically evaluated. The findings show that the model itself is context-dependent and it has to be adapted to the underlying development process. Based on these findings, an improved model is introduced. It is shown that the new model proved to work efficiently and improved the developer-customer communication mechanisms
