A Pattern-Driven Process Model for Quality-Centered Software Architecture Design--A Case Study on Usability-Centered Design

Quality requirements of software systems typically affect large portions of the system, and should be taken into account early in the design process. Patterns have become a mainstream technique to associate frequent quality-related design problems with proven solutions. We present a generic pattern-driven design process model, and apply this to usability, obtaining a usability-centered design process model. As a case study, we have applied the model to the usability-centered software architecture design of a stone crusher control system.
