Plan Inventory Drawdown During a Supplier Transition

A supplier transition can leave a buyer with too much old inventory, too little coverage, or material that still requires approval for use. Procurement should bring planning, quality, and operations together before reducing stock. The working question is how demand, approval timing, and existing inventory interact over the transition period.

In a fictional review, commodity manager Noor says, “The new supplier is ready, so we can stop buying from the old one.” Specialist Grant asks, “Which items are approved for the new source, what inventory remains from the current source, and what demand is firm through the qualification period?” Noor says two items have completed approval, while a third still needs production trial results. Grant replies, “Could planning provide the demand schedule, quality provide each approval status, and inventory control provide lot and quantity records? We can build a drawdown view that shows where a purchase stop is supported and where coverage still needs a decision.” Noor invites the operations manager because one item is used on a seasonal product.

The view should separate available inventory from inventory the plant is authorized to consume. It should also show the owner and next date for each pending approval. A supplier transition remains a coordinated operating decision, so purchasing changes should follow the company's designated approval path.

Practice by drawing three columns titled demand, inventory, and approval. Ask a colleague to give one fact for each column and one uncertain item. Explain which owner needs to resolve the uncertainty before the buyer changes a release.
