On-going continuous learning . Once you start on Agile there is no end of learning! See Reading List for books.

• 2017-01-03: "The Principles of Clean Architecture" by Uncle Bob Martin
• 2016-03-01: "Continuous Delivery in a large Enterprise – Transforming Enterprise IT" by Henk Kolk (Chief Architect at ING Bank). Message is that starting in 2008, ING decided that all their services are being provided as software and that, in fact they are more a software / technology company than anything else (“software is eating the world”). They moved from a traditional waterfall / mainframe / project management approach and moved to agile / devops / continuous delivery of value mode. They have 180 teams developing software, and now do 1500 deployments / week to production (I think, at least that was the implication).
• 2016-02-19: Second Generation Lean Product Development Flow by Don Reinertsen. As usual a very “dense” pitch with a lot of information. If you want to understand impacts of things like queuing theory, lean, and why variability should be preserved for new product development (hint: Black Scholes option pricing model) then this is the video for you. See My notes for more information.

• 2015-11-17: 10 Reasons Estimation and Planning Fails and What to Do About It by Troy Magennis. Great pitch. Love the basics here, such as “If you are in the non-linear region of utilization for your project (i.e. greater than 80% utilization) then estimation will always fail”, “Sometimes you need just enough information to decide what not to do, and perhaps toss a coin for remaining options (if they really are close enough)”, “why this project won't finish on time is because of last project - and no amount of estimating is going to help” and the importance of understanding dependencies. Idea that a lot of bad things happen which increase utilization into the “non-linear” zone and so make estimating useless and forecasting difficult.
• 2015-11-12: Introduction to Micro-services by Martin Fowler. Covers definition (or rather characteristics), when they should be used, and relationship to more general SOA discussion.
• 2015-11-12: Agile is Dead - by Dave Thomas. Agile as originally intended is an adjective, not a noun.
