Many approaches can be used to facilitate the implementation of collaborative requirements in noncollaborative applications. In general, each approach uses different design techniques and has specific objectives and pre-conditions. During the implementation of collaborative requirements, it is not always easy to decide which approach is recommended i.e. which criteria should be used to compare the approaches. Based on the literature, this paper presents a set of criteria to technically compare the existing approaches to support collaborative requirements in non-collaborative applications. The criterion help developers in the task of choosing the most suitable approach to develop collaborative applications based on non-collaborative applications.
