The Disciplined Agile Certification FAQs page was updated. Also you can find more information here PMI New Agile Certification Journey: FAQs (PDF).
I have a comment: DASM training is good not only for “beginning” but also for Foundations of Lean which are rarely described in other sources and for a detailed presentation of Disciplined Agile Delivery process blade. Scrum and other sources do not offer a similar complete picture of the solution delivery process. A good team leader will need also DASM training, not only Scrum and DASSM. The Foundation of Lean is very important for further DASSM training related to Value Stream Layer optimization.
