I am not sure how to interprete your words. Do you mean that the sprint backlog is no longer fixed?
Because that is how we implemented continous flow with some more experienced scrum teams, or with teams using scrum for non-software development.
We used 3 week sprints but dropped the planningmeeting. Instead of one planningmeeting, the PO was coninously planning and asking the team for etimates. He was driven by how fast the team finished ongoing work.
We kept the sprints for having a heartbeat, and to have demo’s of the finished stuff and a retrospective on regular times. Worked well! Jef Cumps
A comment about my Blog entry “The Toyota Production System and Scrum (2)” that puzzles me. It looks cool but on the other side: How do you get the commitment from the team? Just based on the velocity? Do you still care about the idea that every Sprint is a mission. Don’t get me wrong – it works for you. Great! Keep doing it … tell us more about the real story, please.
