This paper gives an account of and analyzes a concept for materials supply within Ericsson Corporation. The study is focused on the customer’s point of view. The concept, called by Ericsson In-House Delivery (IHD), could be identified as a manual form of the principle of Vendor Managed Inventory (VMI). In IHD the supplier has the responsibility for dimensioning the customer’s production store and also for physically replenishing the storeroom without any traditional purchase orders or transactions in IT systems regarding inventory control. This method contrasts with the more traditional Material Requirements Planning (MRP), which is more dependent on data than IHD is. IHD also differ to how VMI normally is implemented using IT-based solutions. IHD could be an uncomplicated method for manufacturing companies to manage non-critical purchased parts or standard parts with low economical importance, and its use could help the company achieve its logistics goals.
