Visualising software architecture with the C4 model

It's very likely that the majority of the software architecture diagrams you've seen are a confused mess of boxes and lines. Following the publication of the Manifesto for Agile Software Development in 2001, teams have abandoned UML, discarded the concept of modelling and instead place a heavy reliance on conversations centered around incoherent whiteboard diagrams or shallow "Marketecture" diagrams created with Visio. Moving fast and being agile requires good communication, yet software development teams struggle with this fundamental skill. A good set of software architecture diagrams are priceless for aligning a team around a shared vision and for getting new-joiners productive fast.

This hands-on workshop explores the visual communication of software architecture and is based upon a decade of my experiences working with software development teams large and small across the globe. We'll look at what is commonplace today, the importance of creating a shared vocabulary, diagram notation, and the value of creating a lightweight model to describe your software system. The workshop is based upon the "C4 model", which I created as a way to help software development teams describe and communicate software architecture, both during up-front design sessions and when retrospectively documenting an existing codebase. It's a way to create maps of your code, at various levels of detail. Static structure, runtime and deployment diagrams are all covered, so you'll be able to tell different stories to different audiences. We'll wrap up the day by looking at the tooling landscape and diagram automation to keep your diagrams in sync with your source code.
