Six-Sigma is a statistical attitude – not judgment or sentiment. It is about statistical facts that as-sist 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 impracti-cable prospects. Six-Sigma is an integrated approach to involve everything within the organiza-tion 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 satis-faction. The primary objective of Six-Sigma methodology is always directed towards the perfec-tion at any level whether financial or non-financial. Putting efforts rightly and maintaining con-sistency 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 in-creasing profit.
