Abstract

The availability, modifiability, performance, and security requirements for a system are difficult both to capture and achieve. Use cases are well recognized as a means for capturing functional requirements but are not appropriate for the specification of non-functional requirements. Achieving a design that satisfies these requirements is even more difficult In this tutorial, we present recent work in both of these areas. We present a characterization of non-functional requirements for the four quality attributes listed. We also present architectural patterns that are used to achieve these qualities. Our characterization is based on the concept of "quality scenario" where each scenario includes a stimulus and an expected response to that stimulus. We present a set of quality scenarios that have been validated against scenarios seen in the "wild" and discuss the concepts behind these scenarios. Explanations of how particular architectural patterns achieve these requirements will also be given.

 

Required experience

This tutorial is oriented toward those who have some experience with software design and development.

 

Expected audience

Those who have responsibilities that involve the specification or achievement of requirements for software systems should attend this tutorial. They will get a systematic explanation of how to specify non-functional qualities and the strategies and patterns that are used by designers to achieve them.

 

Presenter's profile
Len Bass and Felix Bachmann are well-known software architects at The Software Engineering Institute at Carnegie Mellon University. They jointly developed the Attribute Driven Design Method for designing architectures. In addition, Len was a developer of the first scenario based architecture evaluation method (SAAM - Software Architecture Analysis Method) and an author of the popular "Software Architecture in Practice". Both Felix and Len are co-authors of the upcoming book "Documenting Software Architecture".
