Summary of chapter 4: To create an architecture, we must first understand the quality attributes required by the  architecture which will solve our problem.  To do this we must identify the architectural drivers  that matter and are of greatest importance in the problem domain space of concern. But to find these we must find first what are termed system quality attributes – there is however  some ambiguity in the classification and identification of these. So to disambiguate the  confusion we are asked to use a tool the book uses called Quality Attribute Scenarios (Sec 4.3) Architects must first generate, study and evaluate applicability of Quality Attribute Scenarios –  specifically in the areas of: 1. Availability 2. Modifiability 3. Performance 4. Security 5. Testability 6. Usability Architects must communicate concepts with their stakeholders (customers) using general  scenarios to be able to understand the desired Business Qualities and thus the Architectural  Qualities which when put together in the optimal fashion will maximize those Business Qualities  about which the customer cares.
