Abstract: Professional kitchens operate in high-pressure environments where efficiency, consistency, and resource optimization are critical for maintaining service quality. This study examines the impact of lean management practices on workflow performance, waste reduction, and operational coordination across five full-service kitchens. Utilizing a mixed-method approach, the research integrates time-motion analysis, observational checklists, lean implementation scores, and interviews to assess core lean components such as workflow standardization, mise-en-place organization, staff communication, layout optimization, equipment accessibility, and waste minimization. Quantitative results reveal substantial reductions in cycle time, service lead time, and food waste, supported by strong correlations and regression models indicating that communication and standardization are the most influential predictors of efficiency. Principal Component Analysis further identifies a cohesive cluster of lean efficiency practices, with process documentation emerging as an independent but supportive dimension. The findings demonstrate that lean practices significantly enhance operational flow, reduce errors, and improve sustainability outcomes, offering a practical and adaptable framework for performance optimization in professional kitchens. This study contributes to the limited literature on lean application in culinary environments and provides actionable insights for managers seeking to improve kitchen productivity and environmental responsibility.
