Kodsnack 631 - Comfortable in uncertainty, with Barry O'Reilly

Fredrik talks to Barry O’Reilly about software architecture.

Barry has spent a lot of time and energy connecting software architecture to actual code and development work, and finding good ways of actually training new generations of software architects.

Architecture is a level above programming, it is a different skill, and it needs to be properly taught so that more people can think and make active decisions about it. Oh, and architecture happens at a group level. You can’t really do it alone.

Barry’s quest led him to complexity science, a PhD to actually prove his ideas hold up, and two books. The idea that you have to understand what goes on in the code in order to do good architecture is more controversial than one might think.
