Power Sector has always been a key infrastructure, eventhough quality improvements, particularly in the field of operation and maintenance are yet to come on front in many organisations. I would like to congratulate Shri.Kishan Vasekar, REL and his team for their achievements. I am from POWERGRID and I have also started working in the area of improving the maintenance practices by integrating Six Sigma/Lean with ISO. It pays. Regards. M.M.Mehendale
