Root Cause Analysis for a Manufacturing Unit Problem Through Naze-Naze Analysis Technique

This research paper reveals the concept of problem solving tool i.e. Naze-Naze analysis – a cornerstone of Kaizen and the Toyota Production System which is used to systematically eliminate bottlenecks in manufacturing processes which affect productivity. The study carried out in refrigerator manufacturing plant at Faridabad (Hr). Two critical issues were identified through direct shop-floor observation and these are regular detachment of paper tape, leading to repeated replacements and foam leakage at the front-top corner due to notching tool problem. The technique is used to solve both the problems by asking 5-Naze to reach at root cause of the problem which further helps in increasing the productivity.
