That’s interesting, I’ve never observed a scrum team having sprint durations differ in duration between sprints. That would not be healthy and hadn’t realized that was called put as part of ‘sprinting’. Hence as we or i, never vary sprint duration I do use them interchangeably and would b3 very concerned with a team varying length, in one case a team gapped between sprints and it wasn’t defensible so we butted sprints together. I also see team maturing into more leaner behaviour but that’s typically to accomodate larger enterprise like teams from stalling delivery by being consumed with process implementation. Love the article, cheers.
