Amazing days with refreshing our Agile Scrum mindset
We had a two-day in company Professional Scrum Master II (PSM II) training given by Barry. It were amazing days with refreshing our Agile Scrum mindset and a lot of new insights and a toolbox full to facilitate amazing workshops with our colleagues. And I also really appreciated the dry sense of humour of Barry.
Can't wait to see what positive impact we can have with what we have learnt these two days.

Very interactive class, where Barry and Christiaan share their comprehensive

Training was amazing. I wish I could tell the same about PSMII assessment, but it was confusing, frustrating and make me angry, as big part of questions have nothing to do with topic and don't giving any hints in advance (budgeting questions, scaling questions, etc.).
If you want to test me on Scrum - go ahead. If you want to test me on practical implementation of theories in reality - your questions vague and suggest that for all organizations answer should be the same.

The Class was excellent!
Barry and Chris master the framework and are able to add experience and the Liberating Structures to the content. The result are two very interactive days that are filled with theory and practical exercizes.
And because the ‘students’ were very eager to learn and share, the Class got even more immersion.
The location in the Volkshotel in Amsterdam was very okay as well, with a good vibe and also good vegetarian lunch and sustainable snacks.
I got a lot new (and forgotten...) insights and take-aways.
Very well done and thank you very much.

Practical Scrum by the book
Scrum by the book, yet entirely practical. The Scrum.org training takes participants on a journey through the real value of Scrum and Agile. The trainers provide profound insights and plenty of practical experience. Without resorting to theoretical ideology and dogma, they illustrate vividly the traps of zombie Scrum and ineffective pseudo-Agile thinking.
