In this study, lean management techniques are examined from the perspective of how they can minimize operational costs in the manufacturing sector. The growth of cost pressures in industrial production and the need for efficient process improvement strategies were the reasons for initiating this research. The study seeks to explore how lean tools can streamline operations and optimize resource utilization within manufacturing environments.
The research is grounded in lean management principles and explores tools such as 5S, Value Stream Mapping (VSM), Kaizen, Just-in-Time (JIT), and Kanban. To conduct the empirical part, a qualitative multiple case study design was applied to three manufacturing firms in Bangladesh: Bashundhara Paper Mills Ltd. (Tissue & Paper), Incepta Pharmaceuticals Ltd. (Pharmaceuticals), and US-Bangla Leather Product Ltd. (Leather Goods). Data were collected through document analysis—specifically operational reports, process audit records, and lean training materials—and expert interviews with key personnel involved in lean implementation. This provided insight into how lean practices affect cost efficiency and process performance.
The study reveals that lean tools reduce non-value-added activities, lower labor costs, and minimize material waste, aligning with previous research. It emphasizes organizational culture, leadership engagement, structured training programs, and practical recommendations for achieving manufacturing cost reduction.
