Toward model-based requirement engineering tool support

The OpenOrbiter CubeSat Development Initiative is working to build a small spacecraft system using open source software and open hardware principles. Some important design considerations for the CubeSat are nonfunctional requirements. The key contribution of this work is presenting the design of a requirement engineering tool that can be used to speed up the requirement elicitation and specification of system-wide qualities such as availability, performance, and security based on the use of quality attribute scenarios. A prototype application, utilizing the concept of quality attribute scenarios which was originally proposed by the Carnegie Mellon Software Engineering Institute (SEI), was designed and implemented. These quality attribute scenarios are the equivalent of UML scenarios and use-cases. They are built specifically to document the nonfunctional requirements and use a quality scenario template.
