7.7 Summary

System design takes a comprehensive view of the application and the system under design. To ensure that we design an acceptable system, we must understand the application and its requirements. Numerous techniques, such as object-oriented design, can be used to create useful architectures from the system’s original requirements. Along the way, by measuring our design processes, we can gain a clearer understanding of where bugs are introduced, how to fix them, and how to avoid introducing them in the future.
