Shainin Problem Solving for Back Leaky Fuel Injection Pump

Original equipment manufacturers are moving towards achieving zero defect goal and improving the reliability of their products which encompasses the need for introducing problem-solving tools like “Shainin”. This paper is analyzing Shainin methodology for root cause analysis of back leaky single cylinder fuel injection pump manufactured in Production Facility at Bangalore. Shainin approach assumes the existence of a dominant cause of variation and follows a FACTUAL algorithm. The goal of this paper is to provide a critical overview of the Shainin System for quality improvement along with case study, developed over many years under the leadership of the late Dorian Shainin. This paper concludes the effectiveness of Shainin approach towards continuous improvement in quality. Keywords - Shainin, Problem solving, FACTUAL, Paired Comparison, BOB vs WOW
