Like I posted previously, some agile coaches and I have had a few conference calls to talk about scaling agile coaching in the enterprise. During our last call, we answered questions from a Scrum Master friend of mine working with multiple teams in different locations; management wanted month-long sprints, and we talked about common problems with month-long sprints, who should be choosing the sprint length, and some tips on how to help the teams work effectively from a common backlog. I'm happy to report that our advice proved to be helpful, and the teams got the 2-week sprints they desired--it turns out that management was concerned about the "overhead" of sprint planning, review, and retrospectives, and since my friend could explain how the length of the meetings would adapt to the sprint length, the issue was resolved.
I'm also happy to announce that we're having another call on Monday, January 20th at 10:30am Central time. If you're interested in joining the call, contact me for information.
