A Reliable Hybrid Software Development Model: CRUP (Crystal Clear & RUP)

The turning point of software development dates back to 2001 when some specialists published the Agile Manifesto. After that, many companies are moving to Agile methods. However, it seems that in many cases, software teams and companies prefer to use a combination of Agile and plan-driven methods together to take advantage of both discipline and agility simultaneously. In this viewpoint, RUP as a traditional method combined with one or two Agile methods to solve the inefficiency of software development methods against new and changing customer requirements. However, combining such methods may lead to organizational overheads and challenges as well. In this study, having reviewed the most recent attempts to reach hybrid models, a new hybrid model will be presented based on RUP and Crystal Clear. Then, the new model employed in a Case Study. The results showed that this hybrid model has considerable capabilities in small and medium projects compared to its parents' methods.
