Appendix: Key Figures in the Controlling View
In the following all displayed key figures are shortly described.
Number of in-house production operations
Number of in-house production operations that have been triggered.
Number of external procurement operations
Number of external procurement operations that have been triggered.
Number of stock transfer operations
Number of stock transfer operations that have been triggered.
Number of errors
Number of errors that have occurred while processing a Kanban container.
Number of triggering operations
Number of signals, that is, status changes whereby the status of a Kanban has been changed from waiting to empty.
Number of refill operations
Number of refills, that is, status changes whereby the status of a Kanban has been changed from empty or in process to in transfer.
Number of transfer operations
Number of transfers, that is, status changes whereby the status of a Kanban has been changed from in process or in transfer to full.
Number of wait operations
Number of waits, that is, status changes whereby the status of a Kanban has been changed from full or in use to waiting or empty.
Number of replenishment operations
Number of replenishments, that is, status changes whereby the status of a Kanban has been changed from empty, in process or in transfer to full.
Total error time
Sum of the times the Kanban container has remained in the error status. The error time is the time needed to correct the error.
Total trigger time
Sum of the trigger times, that is, times the Kanban container has spent in between the statuses wait and empty. The trigger time is the time elapsed until replenishment has been triggered.
Total refill time
Sum of the refill times, that is, times the Kanban container has spent in between the statuses empty or in process and in transfer. The refill time is the time needed to refill the container.
Total transfer time
Sum of the transfer times, that is, times the Kanban container has spent in between the statuses in process or in transfer and full. The transfer time is the time needed to transfer the container from the supply source to the demand source.
Total wait time
Sum of the wait times, that is, times the Kanban container has spent in between the statuses full or in use and waiting or empty. The wait time is the time the Kanban container spends at the demand source.
Total replenishment lead time
Sum of the replenishment times, that is, times the Kanban container has spent in between the statuses empty, in process or in transfer and full. The replenishment lead time is the time needed to replenish the container.
Average error time
The average error time is calculated by dividing the total error time by the number of errors.
Average trigger time
The average trigger time is calculated by dividing the total trigger time by the number of triggering operations.
Average refill time
The average refill time is calculated by dividing the total refill time by the number of refill operations.
Average transfer time
The average transfer time is calculated by dividing the total transfer time by the number of transfer operations.
Average wait time
The average wait time is calculated by dividing the total wait time by the number of wait operations.
Average replenishment lead time
The average replenishment lead time is calculated by dividing the total replenishment lead time by the number of replenishment operations.
Total target quantity
Sum of the material quantities (target quantities) that would be acquired using Kanban, if with every goods receipt the Kanban quantity defined in the control cycle had been posted for the container.
Total actual quantity
Sum of the material quantities that were actually acquired, that is, for which a goods receipt has been recorded.
Total stock
Sum of the material quantities that are currently available at the demand source.
Number of Kanbans
Number of containers that has been defined in the control cycle.
Kanban quantity
Material quantity, that is, target quantity that has been defined for a container in the control cycle.
Maximum number of empty containers
Maximum number of containers that are allowed to be empty at one time from the point of the supply source. The producer or supplier must ensure that this limit is not exceeded. The maximum number of empty containers is maintained in the control cycle.
Number of Kanbans with status empty
Actual number of Kanban containers that have the status empty.
Number of Kanbans with status full
Actual number of Kanban containers that have the status full.
Number of Kanbans with status error
Actual number of Kanban containers that have the status error.
Actual error time
The most recently measured error time.
Actual trigger time
The most recently measured trigger time.
Actual refill time
The most recently measured refill time.
Actual transfer time
The most recently measured transfer time.
Actual wait time
The most recently measured wait time.
Actual replenishment lead time
The most recently measured replenishment lead time.
Expected replenishment lead time in days
The replenishment lead time in days maintained in the material or control cycle master data. It is used in the Kanban calculation, if the replenishment lead time in hours is not maintained.
Expected replenishment lead time in hours
The replenishment lead time in hours maintained in the control cycle. It is used in the Kanban calculation.
