Abstract: Plan-Do-Check-Act (PDCA) is the cycle of continuous improvement for making small incremental changes. In the present study, root cause analysis has been performed to ascertain the benefit occurred. The die punch inspection gives a brief analysis of the total inspection recorded from the ring crank rejection analysis with action taken. The rejection quantity is presented in percentage from 0%-20%. A brief graph is raised showing a steep decrease of rejection from 15.5 to 15.0 and 6.12 to 0 point. In the starting month, the percentage of defective pieces was higher. After analysis and implementation of PDCA cycle, the rejection rate decreases drastically. In the later months, the rejection rate has been reduced to zero.

Keywords: root cause analysis; Plan-Do-Check-Act; PDCA; continuous improvement.
