Faster, Better, Higher – But How?

One of the main challenges when designing software architecture is the consideration of quality attributes. Not only their design turns out to be difficult, but also the specification of these attributes. Consequently, many problems in software systems are directly related to the specification and design of quality attributes such as modifiability or performance, to name just a few.

Pattern-Based Architecture Reviews

In this IEEE article, authors Neil Harrison and Paris Avgeriou discuss a pattern-based architecture review (PBAR) process to help with system-wide quality attributes. They also discuss how PBAR approach helps with agile practices like frequent releases, changes for user needs, and lightweight documentation. They illustrate the benefits of PBAR process with a real-world project.
