Conclusion<br />
➠ Patterns help<br />
◮ avoiding omissions<br />
◮ covering functional as well as quality characteristics<br />
➠ Method allows stepwise solution of given development problem:<br />
◮ Understanding the problem situation and<br />
decomposing it into several subproblems<br />
◮ Identifying functional and quality characteristics and<br />
instantiating accordant (specialized) patterns as<br />
HCI Frames, and (concretized) security problems frames<br />
◮ Deal with conflicting quality characteristics<br />
◮ Instantiate corresponding architectural styles and<br />
design patterns by a role-driven mapping preserving<br />
specified quality characteristics<br />
➠ Result is a starting point for low-level design and<br />
implementation<br />
