Six-sigma is a business-driven, multi-faceted approach to process improvement, reduced costs, and increased profit and this methodology application in SSI a big change in industrial field. The purpose of this paper is to find the implication of applying six-sigma methodology in SSI, taking a specific case of Hydraulic jack manufacturing industry. It helps to improve quality of product and cost saving. From the literature, this paper help to improve the six-sigma area of application in all types of organization, six-sigma application in Hydraulic jack manufacturing industry in SSI environment. Methodology adopted is DMAIC which is help to reduce the rejection rate of pump head of hydraulic jack set by removing error in process & method of operation. Statistical techniques Gauge R & R method, two sample test, Factorial method, control charts, Process capability analysis before & after application of six-sigma used. Six-sigma mainly implemented in large scale industries, but in this paper six-sigma methodology application in Hydraulic jack manufacturing unit a SSI to improve profit and control high rejection rate of pump head of hydraulic jack set. Application of six-sigma in SSI helps to improve Z-bench Sigma level from 2.21 sigma to5.64 sigma and cost saving of 0.01929 million/annum.

Keywords: Six-sigma, SSI, DMAIC methodology, Manufacturing Industry.
