This is a presentation I did in the 2017 Global Scrum Gathering in Singapore. CSD is a Scrum Alliance certificated course it extend the Scrum learning to including technical practices. The Odd-e CSD class has gone beyond the requirement. After 6 years of teaching it occasionally and continuously experimenting, I learnt a lot.
