How do your teams measure the cumulative value delivered by each story for a feature?
Take, as an example, a story mapping session is done for a feature that generates 100 stories. As teams deliver these stories, the first handful of stories would/should deliver the most value. As iterations go on, the value that the stories deliver would theoretically be less. It’s almost as if the value reaches a limit.
I ask because I remember reading or hearing about how once you reach about 80% of that upper-value limit, it’s probably a good idea to move onto the next feature. Is something that people are actually doing? If so, how are they are doing it?
