Experience Report: A Comparison between Commercial and Open Source Reference Implementations for the Rugby Process Model.

Rugby is a process model for continuous software engineering which allows developers to continuously deliver prototypes and obtain feedback supporting software evolution. There is a reference implementation of Rugby with commercial enterprise tools used in university capstone courses. However, since these tools are expensive, there is a need to study less expensive alternatives which are available on the market to evaluate whether they can be used in Rugby. In this paper, we compare a second reference implementation with the existing one, focusing on the core use cases and non-functional requirements of Rugby.
