Benefits: Participation
Increased Safety, Zero Incident due to this improvement, No. of FTEs were made available for other tasks, Quality, No Rene Flores, Shailendra Choudhari, Heinrich Botha, Amit Parikh, …
Demurrage Cost due to this problem, Waste Elimination, Savings of 0,5 Million AED ++
Standardization: Similar exercise has led to bring more improvements related to Rework Reduction in similar production line. Horizontal Deployment Opportunities (Replication): systems are getting modified to achieve lower manual work esp. where
safety of Employees is at risk.
Single Point Lesson: Innovative Systems Design & Modification can help in reducing Safety Risk ! Remark / Management Comments:
