What is good design and how can we tell the difference between that and bad software design? Extreme Programming introduced some key ideas about software design, that often get overlooked. YAGNI, “You Ain’t Gonna Need It”, and an evolutionary design approach that Kent Beck referred to as "design through refactoring”. YAGNI was aimed at avoiding the over-engineering tendency inherent in designing too far ahead with big-up-front-design. So how do you tread the line between keeping the door open to change, as our understanding of the system grows, vs over-engineering and big ball of mud legacy systems?

In this episode Dave Farley, author of “Continuous Delivery” and “Modern Software Engineering”, explores how to manage complexity in software systems, and how to adopt an evolutionary approach to design that ensures that we can change our software as we learn more.
