Software architecture-centric methods and agile development

摘要

The agile software development paradigm and plan-driven approaches each have their strengths and shortcomings. The former emphasizes rapid, flexible development, while the latter emphasizes project and process infrastructure. Many practitioners, particularly of agile methods, tend-to view software architecture in light of the plan-driven side of the spectrum. They think that architecture-centric methods are too much work, equating them with high-ceremony processes emphasizing document production. But many elements make up a successful development approach, including process, product, technology, people, and tools. Software architecture is part of product quality and isn't tied to a particular process, technology, culture, or tool. This article explores the relationship and synergies between architecture-centric design and analysis methods and the extreme programming framework. We chose to focus on XP because it's one of the most mature and best-known agile practices.
