What’s the name for the estimation method where only one team member estimates at a time?



  • This method is usually used for estimating quickly on a large chunk of user stories to get a feeling on the overall project effort or part of it. I know this estimation method has a name but I have forgotten it. Any clue?

    The process in more detail: The whole team estimates, but only one single team member at a time. If a veto is given by a team member, the one who’s given the veto gives his estimate, allowing the rest of the team to veto again. This continues until no one vetos. In case of a circular vetoing the team members who are disagreeing discuss the task and finally come to an agreement. If no veto is given, the right to estimate is passed on to the next team member.



  • I’ve finally reached out to the person who conducted the estimation meeting in the company where we used that method and he told me to search for “magic estimation”. We used a variation of it. If you search for the method online and read the description, you will find a slight difference: All team members estimate in parallel, though each team member gives an estimate on a different story. The vetoing also is done in parallel.
