Energetic and thought-provoking PSMII class
I took part in the PSMII course with Barry & Christiaan. It was a thought-provoking and energetic class that really helps you to improve and consider your own Scrum experiences.
I would highly recommend the class.

I love the interactive way of providing the training. My first "No Powerpoint" experience, however they used all these flipovers this was very helpful and inspiring.
The training generated a lot of ideas I have to exercise with my own clients.

very interactive and fun way to learn
Christian and Jasper did a great job, very interactive way to learn about the scrum framework, with exercises and continue discussions with the group.
If I should mention something to improve, I would say It becomes at some point too much, as you really need to think and ask questions yourself with no always the assistant of the trainers.
In general, very productive, easy to understand and good opportunity to network !

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.

Sprint Goals are one of the more elusive parts of the Scrum Framework. Most teams know they are important, but few use them - for a variety of reasons. In this post, Barry Overeem and I bust the myth that Sprint Goals are optional in Scrum. And we make an effort to show what makes them so vital in the face of complex work. And more importantly, what you can do to start working with Sprint Goals from now on.

Changing the way we work is extremely difficult — we all know this. It requires us to find novel solutions to wicked challenges, to deal with cultural baggage (‘the way we do things here’) and to bring along the people needed to make a change successful.

Scrum Masters are often understood mostly as “team coaches”. Yet, their role is vastly more important. The Scrum Guide emphasizes that Scrum Masters are responsible for leading and coaching organizations in the adoption of Scrum and causing change that increases the productivity of the Scrum Team.

Scrum is intended as a simple, yet sufficient framework for complex product delivery. Scrum is not a one-size-fits-all solution, a silver bullet or a complete methodology.
