Authors : Kandi Mohamed Amine . Boussoum Hicham .

Abstract

This study provides an empirical analysis of the implementation of continuous improvement practices within Nestlé Waters Algérie, using a process approach and Lean tools such as DMAIC methodology and performance monitoring systems. The findings reveal significant improvements in key metrics, including Overall Equipment Effectiveness (OEE), downtime reduction, and productivity. Nevertheless, the results indicate that these gains are mainly driven by process standardization and performance measurement rather than a deep integration of Kaizen philosophy. The study highlights a gap between the cultural foundations of continuous improvement and their operational application in an emerging economy context. These findings emphasize the importance of organizational and cultural dimensions for ensuring the sustainability and effectiveness of continuous improvement initiatives.
