Currently, your application provides metrics at an aggregate level for lead time, cycle time, work and wait time based on archived cards only. It will be very helpful, if it can provide work time, wait time and cards processed for each team on the board so that each team can see if it is getting better or worse or at same level. If it is getting better or worse then the drill down to the relevant cards will help us determine what caused the improvement / degradation. Your system captures a lot of value timestamps as the card moves. By mining and displaying such metrics, you can drive positive behavior and enhance the software's ability to improve productivity.
