As a software engineers we all know the requirements will change over time. At some point you will need to become comfortable with versioning your NServiceBus messages to adapt to those changing requirements. When you start thinking about the nuances of deploying endpoints that need to handle messages of different versions in flight or in an error queue waiting for retries it can be overwhelming at first. Luckily, there is a straight forward and relatively painless way to make changes to your contracts that will enable your endpoints to process old and new versions in parallel.

Over the years I have read countless management and technical books and of those books there are a select few that had a profound impact on how I view the world and my capabilities as a leader. I have put together this list of books to share so that others can benefit from their knowledge and so I can remind myself of some books I should periodically read.

I developed the Gnome Narrative method over time as a way to both limit the amount of time I spent defining and illustrating projects and as a way to communicate logical designs to non-technical decision makers. Gnome Narratives have slightly more details than a napkin drawing but not much more. Often the diagram can stand on it's own without much description.
