I presented my "Effective Sketches" talk last night at Skills Matter where we looked at how to produce effective diagrammatic representations of software systems and why they are useful. In other words, we looked at how to draw boxes and lines. :-)
Here are the links to the slides and video.
If you missed the talk, I'll be doing a slightly longer version at the upcoming Software Architect 2011 conference, which takes place in London during October.
Simon is an independent consultant specializing in software architecture, and the author of Software Architecture for Developers (a developer-friendly guide to software architecture, technical leadership and the balance with agility). He’s also the creator of the C4 software architecture model and the founder of Structurizr, which is a collection of open source and commercial tooling to help software teams visualise, document and explore their software architecture.
