1. Business-level Strategy

Walmart uses a combination strategy of cost leadership and differentiation. They provide a wider variety of products and services with the same or better quality at a price that is cheaper than their competitors can provide. Walmart concentrates on finding ways to lower their costs by constantly rethinking how to complete their primary and support activities to reduce costs still further while maintaining competitive levels of differentiation. Their successful supply chain management is an important way helping them to implement the cost leadership strategy. They has effective inbound logistics by using just-in-time inventory. And they have cut costs from outbound logistics by creating better fuel efficiency in their trucks, getting more pallets on a load, and decreasing empty miles driven by their trucks (Dess, 2012). Walmart also reduces costs by buying in large blocks. Technology plays a key role in Walmart’s supply chain too, it allows Walmart to accurately forecast demand, track and predict inventory levels, create highly efficient transportation routes, and manage customer relationships and service response logistics (Walmart's Keys to Successful Supply Chain Management, 2013). In conclusion, Walmart's successful overall cost leadership/differentiation strategy leads to high entry barriers for competitors.
