Exploratory research: The Optimization of warehousing operations for increased efficiency and cost reduction. A case study of Decathlon's Warehouse

Abstract

This thesis explores how to optimize warehouse operations to improve efficiency and reduce costs, using Decathlon’s warehouse in Morocco as a case study. The research followed an exploratory approach, combining interviews, field observation, and internal data analysis. Each warehouse process was examined step by step to identify key issues and suggest targeted improvements. Solutions focused on reducing costs—especially in the picking process—through better labor planning, information sharing, and the introduction of a third shift. Some investment was also recommended to expand storage capacity and handle peak periods more effectively. To support these proposals, several analytical tools were used, including RACI, SWOT, risk, and shift matrices. Warehouse performance was also benchmarked against global standards such as the WERC metrics, and Frazzelle’s performance model was used to structure the efficiency evaluation
