Reusing non-functional patterns in i∗ modeling

Patterns are an important concept for capturing and reusing Non-Functional Requirements (NFR) knowledge. This paper reports on the use of NFR patterns as a means for reusing cataloged information. In particular we stress its use for intentional models written in i*. This paper focuses on the NFR awareness and details some of its patterns. The integration with i* is done by means of specification patterns, which integrates the cataloged information with the i* model. An example is shown as to argue about the feasibility of our proposal.
