The warehouse has issued materials, the process has started and the final process has been completed, describing different stages respectively. Directly subtract these records to obtain the quantity in production, which will jump when encountering supplementary recording and cancellation. The Kanban board must explain the statistical scope, deadline and business events on which it is based.

How to arrange records and operations

Establish in-process status according to work orders and processes, and quantity changes come from verified receipt, transfer, scrap and output records. For data entered late, the occurrence time and registration time are saved. The real-time view can prompt for records to be synchronized, and settlement reports use the confirmed statistical snapshot.

The work-in-progress details need to show the location of the process, not just the total quantity of the entire factory. Waiting for inspection, suspended processing and waiting for transshipment may all be considered in-process, but they will affect the arrangement of different positions. Products with different units cannot be added directly to form a meaningless quantity. Reports can be summarized by material, work order and status to clarify whether outsourcing is included. For cases where the work order has been completed but there is still a balance in process, a check list will be formed to find out whether the records of returned materials or scrapping have been omitted.

Specific scenarios that need to be checked

For example, if the completion record of the night shift is added the next morning, querying yesterday’s snapshot and the current view should be able to explain the difference. Test undo reordering and rework reflow, and check whether negative numbers appear. Click on the summary value to see the detailed source, which is more helpful for on-site verification than just displaying a dynamic number.
