Situation
Multi-Store Demand Forecasting Optimization
A global retail chain with 500+ stores struggling with inventory optimization, demand prediction accuracy, and managing complex seasonal variations across diverse product categories.
Client Context
International retail operation spanning multiple regions with diverse product catalogs, seasonal variations, promotional activities, and complex supply chain requirements demanding sophisticated forecasting capabilities.
Complication
Key Challenges
- Inaccurate demand forecasting leading to 35% stockouts
- Excess inventory carrying costs of $18M annually
- Complex seasonal patterns across different regions
- Limited visibility into promotional impact on demand
- Manual inventory allocation processes
- Poor customer satisfaction due to product unavailability
- Inability to factor external variables like weather
Technical Constraints
- Legacy POS systems with limited data exports
- Inconsistent data quality across store locations
- Real-time processing requirements for 500+ stores
- Integration challenges with existing ERP systems
- Scalability requirements for millions of SKUs
- Limited machine learning expertise in-house
Business Impact
Poor demand forecasting was resulting in $18M in excess inventory costs annually, while stockouts were causing an estimated $12M in lost sales and significant customer satisfaction issues.
