SURAJ DEO PRASAD

In Iron making i.e at Blast Furnace, it works with two Sigma and intrestingly, non of top management chalanged this and never asked raise sigma rating. Actually Sigma rating is the tollarance So, sigma rating which is a parameter judge your defect rate varies from Sector to Sector. For example, in auto sector equipment need to operate at higher sigma to avoid rejection which is otherwise is very costly while on the other hand in a Granite crusher unit you can operate equipment at lower sigma and not loosing much. Raising sigma level even for a single point call for investment. So, decide cooly, do you really need to elevate your Sigma level. On the other hand, 5-S concept is just like "KAR SEVA". No investment but high return. High return in term of increase in Equipment availability, boost in moral of working people and increase in space availability for further productive job. BUT you need to keep asking your staff/ Operator to clean, clean and clean...
