Every 10 Days 1. record the sprint’s velocity 2. remove the story-cards from done 3. do a retrospective

Velocity ==Sprint:2, Day:10
Clarifying...Anyone’s 1 can create a new backlog story-cardAnyone’s 1 can split a backlog story-cardA story-card on a work-table can only be worked on or split by 1’s thrown on that work-tableEveryone’s dice have to be thrown at the same time and the 1‘s used at the same timeCheck for bugs only on story-cards on work-tables (not in backlog, not in done)Anyone can check for bugs on any story-card
Varying...Number of dice per personNumber of workers per tableNumber of work tablesCost of making a story-cardCost of splitting a story-cardCheck for bugs on backlog story-cards tooLikelihood of a bug
Measuring...Flow number of days a story card takes to get to doneWaste unrolled dice per sprint 1’s that could not be used per sprintWork total number of 1’s thrown per worker total number of 1’s thrown per sprint
