Most software architects represent the environment in a very static way, and from that static representation, produce static software. As a result, the software structure they create is like a picture of a picture…used to describe what is actually a movie. This problem, rooted in a mechanistic worldview, is where Barry O'Reilly’s Residuality Theory was born.

Residuality Theory - in very few words - is a method of designing software architectures inspired by how the most talented architects do it: i.e. starting from the stress conditions that the system could eventually face as it operates.

Barry O'Reilly is a software architect with 25 years of experience in the IT industry. He has held leading roles at global software companies and has spent many years educating architects and he is currently pursuing a PhD in Complexity Science and Software Engineering at The Open University.

Residuality theory looks at the world not as a bunch of static things or still pictures, but as a constantly moving set of processes which we can't really see and grasp. It requires designers to move away from a static view of the system: by letting the architecture design be inspired by its “stressors”, O'Reilly thinks that not only can we design more resilient systems but also more efficient ones.

In this episode Barry also describes the philosophical background behind the theory and why Residuality can be a viable approach to designing organizations too.
