Playbook: one sub-assembly runs late, the finished product slips

The situation

The board sub-assembly MO-DEMO-PCBA-1 was supposed to finish before the final assembly MO-DEMO-S100P-1 needed its boards for operation one. It didn't: the reflow step is still running. The final assembly still shows its original dates. Nobody has worked out the new finish date — and that is the date the customer will eventually ask for.

The screenshots come from the Otiox demo workspace. To follow along, choose Switch to demo in the sidebar — changes there never touch your live data.

Step 1 — See the cascade

Go to Inventory → Stock Integrity and open Child MO delays parent.

Child MO delays parent: the sub-assembly finishes after the parent needs it

The finding links the two orders: the sub-assembly finishes on 2 October, but the final assembly needs it for operation one on 29 September. The parent slips about three days unless it is re-planned or the sub-assembly is expedited.

Step 2 — See how late the parent will be

Open MO not released on time for MO-DEMO-S100P-1.

MO not released on time: started now it ends four and a half days after its planned end

The parent was planned to start on 29 September and is still scheduled. Started now, it ends four and a half days after its planned end. What to do: release it now, or re-plan its end.

Step 3 — Re-plan the parent

Choose Move MO finish date under Fix.

Schedule Manufacturing Order: new start and end dates

Set a start and finish the boards can support — in the demo, 5 to 7 October — and choose Schedule Order. The final assembly now carries the date it can actually meet, and that is the date to give the customer. On the next scan the findings close by themselves.

If the date matters more than the plan, work the other way: open the sub-assembly and finish its remaining operation first. See the Stuck Orders playbook.
