Bob Greene: There are two laws of software architecture that we codified. The first is that everything in software architectures are trade off. And the second law was that the why is more important than the how, he says. Greene: We stress this idea of creating lightweight documentation to capture why when you do make these decisions.
“Everything in software architecture is a trade-off, and the why is more important than how."
Neal Ford is a Director and software architect at ThoughtWorks. In this episode, we discussed all things about software architecture covering his three most recent books: “Fundamentals of Software Architecture”, “Software Architecture: The Hard Parts”, and “Building Evolutionary Architectures”. We first discussed the definition of software architecture and how it relates to software design. Neal then described the two important laws of software architecture related to trade-offs and the why. Neal then explained why software architecture is difficult and discussed the hard parts, such as finding the least-worst combination trade-offs, understanding the importance of data, and managing coupling. Towards the end, Neal shared about the evolutionary architecture concept and some of its principles to support making incremental change across multiple software architectural dimensions.
