Six Sigma within small- and medium-sized enterprises (SMEs) is rapidly emerging as the new wave of change in Six Sigma. The methodology adopted is Define, Measure, Analyze, Improve, and Control (DMAIC) of Six Sigma which had been mostly successful so far in large-scale industries. The methodology has been applied to reduce the rejection rate of the engine mounting bracket (EMB) by reducing defects inherent in the processes. The application of Six Sigma project recommendation brought up the process sigma level to 5.24 from 1.64 by reduction in EMB hole diameter variation in the process of machining after die casting. This increase in the sigma level is equivalent to a monitory saving of Rs. 0.260 million per annum which is a noteworthy figure for an industry of such level. This paper provides documented evidence of Six Sigma implementation in a die casting manufacturing unit which has been taken as a representative of a small- and medium-size industry.
