What is Kanban Maintenance?
Over time, the consumption of materials managed by kanban can vary. As a result, it may become necessary to update the sizing of kanban loops by adding or removing cards.
Consumption maintenance
The Consumption maintenance proposes the scaling down of a kanban loop based on the consumption recorded by KanbanBOX in the last period, normally the last 5 Lead Times.
Procedure:
- Get in
Kanbans >
Kanban maintenance >
Maintenance from consumptions;
- In the table Kanban loops maintenance from KanbanBOX statistics check the Maintenance alert and check the Adjustment needed and the Suggested adjustment;
- Resize from the Operations column.
How to read the table fields useful for resizing
The table contains a series of fields that refer to the loop master and specific fields for performing maintenance.
Field | Description |
---|---|
Average Real Lead Time | Represents the average real Lead Time of the loop. The real Lead Time of a kanban card is calculated as the difference between the ![]() ![]() |
Comparison between average real LT and current loop LT | Represents the percentage difference between the Average Real Lead Time and the Lead Time of the kanban loop. |
Maximum consumption per day from KanbanBOX | Represents the maximum daily consumption calculated with the moving average on Lead Time. The quantity of consumed material is detected when an available card is declared in the state ![]() ![]() ![]() |
Adjustment needed | It represents the percentage scaling necessary to have a sizing perfectly aligned with the detected consumptions. |
Suggested adjustment | It represents the number of cards that are suggested to be added or removed from the kanban loop to get closer to the correct sizing (the resizing may slightly differ from the necessary resizing since the increases/decreases are made of discrete units). |
Maintenance alert | Visual alert useful to filter the loops for which it's suggested to increase/decrease the number of cards. The icon ![]() ![]() |
Change in stock value | It represents the economic impact on the total of the stock in the warehouse if the resizing suggestion is accepted. To view it, you must have completed the Statistical cost parameter in the advanced fields of the part master data. |
Operations
The operations you can perform to resize the loop are:
-
: each click increases by 1 the number of cards in the loop;
-
: with each click, you reduce by 1 the number of cards in the loop;
-
: by clicking, the link will be resized according to KanbanBOX suggestions;
-
: link to the statistics page (see the guide Kanban loop statistics);
-
: to access the page Edit your kanban loop.
Maintenance import
To carry out a massive adjustment of the loops due to changes in the parts' consumption already provided (for example for a product with seasonality), it's possible to import external data.
To do it, it's mandatory to enter the partner identification code in the partner database (field Partner number, see the guide Create and update a partner).
Procedure:
- Log in
Kanbans >
Kanban maintenance >
Import consumptions;
- Click on the link kanban_maintenance_import_cons.xls to automatically download the Excel file. Once downloaded, open the file and enter the consumption to be imported. Follow the instructions on how to compile the file shown in the Help sheet (it is not mandatory to keep the name kanban_maintenance_import_cons.xls);
- Save the file and upload it by clicking on Choose file in the field Excel file for consumption data, then click on
Import consumption data;
- Resize.

Maintenance from import.
The table contains a series of fields that refer to the kanban master and specific fields for performing maintenance.
Field | Description |
---|---|
Maximum consumption per day from KanbanBOX | Represents the maximum daily consumption calculated with the moving average on Lead Time. The quantity of consumed material is detected when an available card is declared in the state ![]() ![]() ![]() |
Maximum consumption per day from import | It is the imported data. |
Adjustment needed | It represents the percentage scaling necessary for aligning the sizing to the imported consumption. |
Suggested adjustment | It represents the number of cards that are suggested to be added or removed from the kanban loop to get closer to the correct sizing (the resizing may slightly differ from the necessary resizing since the increases/decreases are made of discrete units). |
Operations
The operations you can perform to resize the loop are:
-
: each click increases by 1 the number of cards in the loop;
-
: with each click, you reduce by 1 the number of cards in the loop;

: by clicking, the link will be resized according to KanbanBOX suggestions;

Resizing actions
The Operations possible are:
-
: each click increases by 1 the number of cards within the loop. A kanban card in the state
New in created in the board;
-
: with each click, you reduce by 1 the number of cards inside the loop. The number of cards on the board doesn't decrease immediately, but only after the release of a card in the state
Full;
-
: by clicking, the link is resized according to KanbanBOX suggestions.
