I am also the author of the best-selling book on Amazon, "Essential Scrum
." As a certified Scrum Trainer, I have trained more than 20,000 people with a special focus on corporate on-site training.
I've worked with hundreds of companies teaching agile software development using Scrum, ranging from start-ups to the Fortune 10. I was the first managing director of the worldwide Scrum Alliance, too.
I am also the creator of the Visual AGILExicon®
, a library of vibrant, colorful images that offer three-dimensional representations of agile and Scrum concepts, freely available for the agile development community to license and use.
