Increasing the organisation's productivity can directly affect operational and financial performance and is regarded as a crucial tactic for achieving industrial excellence. Productivity is a fundamental metric that affects work-in-progress inventory, production, process utilisation, product cost, and on-time delivery. Hence, engineers and managers are under a lot of pressure to improve organisational performance. The Man-to-Machine-Ratio (MMR) was changed from 1:1 to 2:1 to improve machine coverage and increase the Mark, Scan, and Pack (MSP) process performance for product line X. However, this modification has resulted in a lower productivity output of only 4,000 pieces per man-hour compared to the management objectives of 6,000 pieces per man-hour. In this study, the researchers have concentrated on increasing the Personnel Efficiency (PE) at the MSP process while identifying Non-Value-Added (NVA) activities. To increase productivity, the researchers used the Define, Measure, Analyse, Improve, and Control (DMAIC) technique of the Lean Six Sigma process. A detailed examination of work procedures, motion, and time was carried out to classify jobs as Value-Added (VA) or NVA using work study tools and Kaizen worksheets. The results showed an increase in production from 4000 to 6000 pieces per man-hour by reducing labour steps and improving the MMR from 2:1 to 1:1. The study's findings demonstrate that lean Kaizen techniques and work element analysis have been successfully used to enhance PE and productivity in manufacturing operations.
