Excellent!
Barry and Christiaan made this training an tangible and extremely worthwhile learning experience. I took a lot out of it, not just content-wise but also in how a brilliant training can be structured. Thank you for all the good memories and Aha! moments.

Training was amazing, but assessment sucks!
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.

A golden combination
The combination of Daniel Vacanti and The Liberators is golden. They give a great mix of theory and exercises. This class is a must for everyone working in a scrum environment.

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.

Energetic and thought-provoking PSMII class

I would highly recommend the class.

Perfect format for collaborative learning
Interactive with lots of opportunities to learn from the wisdom of the group. Teachers are open to questions and remarks. The class itself is kind of an awesome changing Framework for transferring scrum knowledge to be filled by the group.

Barry and Christ facilitate this 2-days class really well. They added lots of fun games to small groups, and motivate us to have lots of reflection together after each game to think about how to put into use in the workplace. You will NEVER be bored with a professional group. Highly recommended.

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.
