Demand Analytics: Automating Forecasting to Increase Product Availability and Reduce Inventory

The Client

The client is a large supermarket chain with over $20 billion revenues.

The Challenge

The client was facing a significant challenge with store stockouts while also experiencing excess inventory situations, particularly for general merchandise and import items. The root causes of these challenges were high forecast errors and disconnects between forecasting and replenishment.

The Solution

Core Compete conducted diagnostics to identify process changes and solution capabilities needed to improve forecasting and replenishment. It deployed SAS Forecasting to automate the statistical forecasting process. It also developed a retail forecasting methodology for store-SKU-week forecasting.
