currently i am facing a proble, where the planning and purchasing department quarreled over the shortage of stocks in purchasing. They are using the MRP system. My question is, is the Kanban System suitable in solving this problems, where many components are involved.
Thanks for all the suggestions.

Like most things the answer is, “it depends.” Kanban systems are very effective to replenish supply but require knowledge of lead times, estimated consumption/demand quantities and pretty reliable delivery of the supply. I can only speak from experience but having thousands of components or more in a kanban system can work just fine, although I haven’t done one with millions of SKUs. MRP planning usually does worse when the above information is not accurate or demand cannot be statistically planned. Both systems suffer in low demand situations and tend to drive to higher inventories. There are a few alternatives but email me separately and we can discuss further if you would like.

Gather data on what the majority of understocks are, and find out lead times, varying usage rates, and average usage rates and see if you need to change average stock levels. If this information is wrong, even if you used kanbans, you’d run out of stock.

Nitin DixitParticipant@NitinDixitInclude @NitinDixit in your post and this person will
be notified via email.Agree with Chris. Demand pattern (Vol varience, mix varience, lead time) and supply reliability (inter consignment time, lead time and their variability) an quality reliability are the first things to determine.
@amylee do consider that creating a pull is the fourth principle of lean and is useful after value stream and Flow are addressed.0 -
