Industrial enterprises under intensifying global competitive pressure face a persistent structural problem: hidden operational losses, or Muda, that inflate prime unit costs and erode profit margins even when output targets are met. This article investigates how systematic application of the Kaizen philosophy of continuous incremental improvement can diagnose, measure, and eliminate the seven classic types of production waste across manufacturing lines in a transitioneconomy setting. The study combines Value Stream Mapping with a calibrated Monte Carlo discreteflow simulation of five parallel production lines observed over a twenty-four-month improvement cycle, contrasting a six-month pre-Kaizen baseline with a post-implementation steady state reached after sequential rollout of five-S and visual management, standardized work with single-minute exchange of die, and Kanban-based pull scheduling. The diagnostic framework tracked Process Cycle Efficiency, Overall Equipment Effectiveness, defect rate, work-in-progress inventory levels, and unit production cost before and after the intervention. Findings show total lead time fell by roughly seventy-two percent, work-in-progress inventory by seventy-four percent, and the defect rate by over half, while Overall Equipment Effectiveness rose from sixty-six to seventy-nine percent and unit production cost declined by nearly seven percent, lifting operating margin by almost six percentage points. Decomposition by improvement bundle revealed that standardized work and setup-time reduction delivered the largest quality and flow gains, while pull scheduling primarily compressed inventory. The results confirm both research hypotheses and clearly demonstrate that Kaizen-driven waste elimination yields measurable, replicable operational and financial benefits, offering industrial managers in transition economies a validated, low-capital pathway toward sustained long-term competitiveness.
