Abstract

This study investigates the implementation of lean manufacturing (LM) in the Lebdah Cement Factory (LCF), Libya, to assess its impact on operational performance. Using a structured questionnaire distributed to 118 employees, the study examined the application of LM principles, particularly in minimising the seven wastes. Statistical analysis revealed a strong positive relationship between LM adoption and process performance (Pearson r = 0.83; β = 0.711, p < 0.001). The findings highlight that despite contextual challenges, LM significantly improves production efficiency in the Libyan cement industry. This study contributes to the limited empirical literature on LM in developing economies and offers practical guidance for managers seeking operational excellence in resource-constrained environments
