Taping Parts (Outsourced Taping vs. Hand Placing)
Rejected Parts @ incoming inspection - Miss-labeled, wrong part
Wrong part - Documentation
Customer Supplied Parts On Time
Programmed Parts Issues
Schedule - Unsure of "Due Dates" both internal and external
SO Due date does not necessarily reflect customer expectations (Pull in & Push out)
Information re: schedule not necessarily shared universally
Unknown production lead time (Days vs. weeks)
stencils
receiving
Sub Assemblies - Un clear process to Create W.O.
Parts Shortages - Scrap Allowance, Inventory Accuracy
Purchasing
Supplier/ MFG Lead time
Customer Pull in of Ship Date - Rebuy/re-schedule parts
Schedule Discipline - Parts shortages due to changes in schedule (If MRP tool is checked and used correctly when W.O. is moved this should be ok)

In reading through the Feb 19th entry, I'm not sure that the current way we use MRP that you can depend on your last statement in that entry to be correct. From recent discussions with Rod and Dad, it came to my attention that purchasing does not use MRP to know what to buy that day (which is what I thought MRP's primary function was for purchasing). MRP is only used to alert a buyer who is purchasing a part for a specific job that there are other demands for that part, so purchasing qty can be adjusted to buy all qty's the MRP system shows need to be purchased.
ReplyDeleteSo, as schedules move in our current use of MRP will not alert us to adjust those PO's. Expediting is expected to pick up on all this. From the outside, this seems to be a cumbersome method and may cause us to wait too long before things hit the expedite window before we react.
That's my two cents,

In general I agree with your process assessment. And I think the idea of MRP telling purchasing what components to buy each day is a good idea, but we are not currently there.
ReplyDeleteI think what Rod was trying to point out is that when people move work orders up they need to be disciplined about checking the MRP tool in order to adjust the schedule to suppliers in advance of expediting. Right now I think the philosophy is move it up and see if we get parts or not. while holding off from telling the customer until we do or don't have parts so that we can give them a definitive answer on meeting their ship date.
