Vendor Managed Inventory (VMI) is a streamlined approach to inventory management and order fulfillment. VMI involves collaboration between suppliers and their customers (e.g., distributor, retailer, OEM, or product end user) which changes the traditional ordering process.
The goal of VMI is to align business objectives and streamline supply chain operations for both suppliers and their customers. The business value is a direct result of increased information flow:
The basic Vendor Managed Inventory (VMI) process can be described in terms of the following steps: data communications, calculations, monitoring and reporting.
The VMI process starts with the customer sending a Product Activity Report (1). This report contains demand information such as sales and transfers, along with inventory position information such as on-hand, on-order and in-transit for the items that changed since the last report.
The VMI software analyzes the data and creates recommended replenishment orders (2). The recommendations are based on algorithms which use factors such as forecasts, frequency of sale, and dollar velocity of sales. Ideally, these processes include:
The supplier's planner reviews the recommended orders and any exception conditions before approving appropriate orders (3). The VMI system then sends:
When trading partners begin VMI, they start by agreeing upon objectives for:
The system monitors actual activity with measurements against those objectives. The system must report the same information to both the supplier and the customer so that the process is highly transparent. Information should always be available to both parties on demand. Ideally, the VMI system should also provide exception alerts to both parties when measurements get outside an acceptable range or when a problem with the data appears.
As with most mission-critical operational systems, “the devil is in the details” when it comes to performing VMI. In order for this seemingly simple process to run smoothly, several important capabilities are required:
With VMI, we now see demand real-time, as it happens. In the past, we relied on customers to communicate what was going on and identify issues – then we had to react as best we could. Using VMI, we have the visibility to anticipate demand fluctuations and respond in a timely and cost-effective manner.
