Requirements monitoring frameworks: A systematic review

We conclude that most existing approaches are restricted to certain kinds of checks, particular types of events and data, and mostly also limited to one particular architectural style and technology. This lack of flexibility makes their application in an SoS context difficult. Also, systematic and automated variability management is still missing. Regarding their evaluation, many existing frameworks focus on measuring the performance overhead, while only few frameworks have been assessed in cases studies with real-world systems.
