Six-Sigma is a statistical attitude -not judgment or sentiment. It is about statistical facts that assist the authorities to spotlight their concentration on the progression arrangement rather than on individuals and get assessments based on reality and unbiased information but not on impracticable prospects. Six-Sigma is an integrated approach to involve everything within the organization for reducing defects and variation. It is a combination of all efforts in an association for quality enhancement, quality progress and quality protection to reach the optimum clients satisfaction. The primary objective of Six-Sigma methodology is always directed towards the perfection at any level whether financial or non-financial. Putting efforts rightly and maintaining consistency are the basic concepts behind successful implementation of Six-Sigma. The present work provides a way to examine the Six-Sigma practice in a manufacturing firm with the use of statistical thinking in getting high quality products by reducing the variation and ultimately increasing profit.
