The Quest for the Golden Pipeline

A guided tour of a modern continuous delivery process, along with the benefits and challenges it presents - focused on Value Stream Mapping, Quality Assurance, Automation and Measurement.
I’m a visual person, when I started out with build and release engineering and agile, charged with reducing cycle time I wanted a holistic view of the current system and a path to tackling the issues. I've since learned much more about the practice of value stream mapping and how it can help tune your delivery process.
