This article describes how several operations research tools, notably Data Envelopment Analysis (DEA) and Value Efficiency Analysis (VEA) were applied to the long-term development of S-Group’s Prisma Hypermarket chain in Finland. Based on different metrics, relevant DEA and VEA models were implemented to identify efficient and inefficient units. Reasons of inefficiency along with suitable suggestions for improving the inefficient units have also been discussed.
