Jeff and I have been working on the next revisions to the Scrum Guide. We will be presenting a webinar about it within a month or so.
We first presented and published Scrum in 1995 at an OOPSLA conference in Tampa, Florida. Almost twenty years have passed. Agile and Scrum have succeeded far beyond our expectations. Actually, we never had expectations beyond using Scrum for ourselves, so anything more was easy.
Between 1995 and the publication of the Agile Manifesto in 2001, Mike Beedle, Martine Devos, Mike Cohn, Deborah Stenner, Tonya Horton, Will Smith, and Alan Buffington all moved Scrum forward, using it and helping us refine it.
After 2001, I started holding Scrum training classes, first called Scrum, then Scrum Master, then Certified Scrum Master classes. Some of the people in those classes had epiphanies. They wanted to help spread Scrum through training and consulting. Some of them (and certainly not all) are Jens Ostergaard, Bob Schatz, Clinton Keith, Boris Gloger, Kane Mar, Peter Borsella, Roman Pichler, Pete Deemer, Will Menner, Gabrielle Benefield, Jim York, the whole group at Citerus in Upsula, Sweden, Alan Shalloway, Michael Vizdos, Hubert Smits, Jean Tabaka and many, many others.
All of us should admire these people. When they started, waterfall was the norm. Scrum was viewed as inadequate and full of holes. These pioneers were often insulted, called fools and stupid, accused of spreading ideas that would hurt customers, and worse. They spoke at conferences and held classes, most to very small audiences. Even then, most of their time was spent answering waterfall vs Scrum arguments.
I thank them for seeing the light, taking the risk, and improving our profession alongside Jeff and myself, and the rest of us in the agile movement.
