The key figures for the time sequence of the process are determined per control cycle for a Kanban container and can therefore be aggregated upwards. The average value can be determined for each key figure.
The illustration
Sequence of the Status Changes in KANBAN gives you an overview of the status changes.Refill time
The refill time is the time that the Kanban container spends in between the EMPTY and IN TRANSIT status, that is, the time needed to refill the container.
The average refill time is calculated by dividing the Total refill times by the Number of refill operations.
Trigger time
The trigger time is the time between the WAIT and EMPTY status, that is, the time in which the replenishment is triggered. The trigger time can only be calculated if the WAIT status is used.
The average trigger time is calculated by dividing the Total trigger times by the Number of trigger times.
In transit time
The in transit time is the time that the Kanban container spends in between the IN TRANSIT and FULL status, that is, the time needed for transit.
The in transit time can only be calculated if the IN TRANSIT status is used.
The average in transit time is calculated by dividing the Total in transit times by the Number of in transits.
(Total) Replenishment lead time
The replenishment lead time is the time spent between the EMPTY and FULL status, that is, the time needed to replenish the container. The replenishment lead time is calculated by adding the total refill and in transit time.
The average wait time is calculated by dividing the Total replenishment lead times by the Number of replenishment lead operations.
Error time
The error time is the time that the Kanban container spends in the error status.
The average error time is calculated from the Total error times and the Number of errors.
Wait time
The wait time is the time that the Kanban container spends with the user, that is the total time the container spends in FULL, then IN USE and finally WAIT or EMPTY.
The average wait time is calculated by dividing the Total wait time by the Number of wait operations.
Number of replenishment operations on the same day
The key figure No. repl. ops. same day is also used for evaluating the time, because in KANBAN, the time is measured on a daily basis, that is, a status change on the same day is not taken into account.
The key figure No. repl. ops. same day supplies the number of replenishment operations that take place on the same day, on which the container status was set on EMPTY.
