Managing Peak Season with VMI

A lot can go wrong when it comes to managing the inventory and supply chain demands of peak season. Supply chain managers need to react to seasonal peaks and sudden changes involving stock levels whether from the holiday season, promotions, or external events such as shipping-related issues from strikes, capacity constraints at carriers, weather-related delays, or any other supply chain disruptions.

Fortunately, vendor-managed inventory (VMI) programs support the many demands of managing the orders and volumes of peak season. VMI is an inventory management technique in which a supplier of goods, usually the manufacturer, is responsible for optimizing the inventory held at the customer’s location, typically a retailer or distributor.

EDI & VMI: the key to demand driven supply chains

EDI is a foundational element of VMI programs which allow trading partners to share inventory data and create a “push” or demand-driven supply chain with lean inventory levels. VMI programs also require careful management of the supply chain, aided by frequent deliveries and demand forecasting with some degree of accuracy.

The concept of collaborative replenishment takes VMI to the next level with advanced technologies such as cloud, mobility, big data analytics, and even AI. This means that trading partners have more flexibility and greater communication capabilities via data sharing to truly collaborate, even empowering a partner to suggest or recommend an order.

Collaborative replenishment tools allow suppliers and their sales channels to meet two critical challenges of peak season:

Minimizing inventory shortages & disruptions

Stock coverage is a key KPI to monitor in any shared procurement management environment. Suppliers and their trading partners need to manage disruptions during peaks, often in real-time. Suppliers need to limit excess inventory in their channels while preparing for unexpected surges in sales or disruptions that can cause early shortages.

Features of collaborative replenishment systems may include truck building and the ability to pool resources like warehouses and trucks among suppliers to optimize inventories and reduce transport costs. Trading partners may also have access to inventory allocation and available to promise (ATP) planning features to further optimize inventory levels.

The Generix Collaborative Replenishment smart platform enables automatic calculation of PO quantities to cover the customer’s consumption (sales out from the DC to stores) until the next possible delivery date. Suppliers can easily experiment with different scenarios to optimize stock levels against demand. Logistics providers often use the solution for pooling capabilities to simulate stock-out analysis via a powerful computation engine.

Accurate demand forecasting

Consumption forecasting, also known as demand planning, is another critical KPI in co-managed environment. Going beyond just accurately identifying inventory levels, a replenishment solution must provide reliable consumption forecasting in order to make future supply calculations.

Forecast calculations are typically based on sales history, and must take into account past shortages, while integrating any new information from trading partners as well as available external information, such as weather or consumer-related data. Advanced collaborative replenishment systems can draw from various types of demand signals with enhanced analytics tools which may even incorporate external information from third-party data sources like weather and Census-demographic information to sharpen demand planning accuracy at the regional, city, store or SKU level.

As a result, when demand changes due to marketplace events, promotions or supply chain disruptions, suppliers can build better forecasts and then proactively manage the supply chain. They can head off stock-outs and respond to disruptions (whether anticipated or unexpected), or prepare for changes in demand patterns from happenings such as trends, sporting events, cultural events and holidays.

The results are in

Reduced inventory levels, optimized transportation, improved customer service and increased sales volumes are among the many benefits of using collaborative supply management. Worldwide, Generix customers using our stock replenishment-collaborative replenishment EDI-based solution have reduced shortages by 30% while lowering transportation costs by 15% on average, thereby increasing sales by more than 10% to 24% on average.
