With 9 years of experience working in an agile environment, I’ve implemented Scrum and Kanban with a variety of teams. My experience has primarily been as a product owner on a scrum team, though I’ve filled in with scrum master duties as well. I’ve coached others on user story writing and backlog prioritization.
Most importantly, in my opinion, I’ve changed all of the things that I’ve done. My teams have experimented with multiple structures and variations on frameworks to find what works best. Many two-week experiments yielded great results. Some of them, not so much. When they don’t work out, we always learn something and move on to the next experiment.
