Abstract

The present dissertation work was carried out in an XYZ industry in order to reduce the variability in the
control rack milling process after the identification of the issue through various trials & techniques. Basically the XYZ
industry faces a severe issue with one of its major long standing customers. The issue being a rapid increase in the
rejection rate of the 2 types of pumps that the plant manufactures, namely the A08 & 939 types, which are special
purpose ones used in the diesel engine of tractors. The rejection rates have been predominantly observed to have
followed a trend or a pattern over a period of time. The customer defines the problem as an hunting issue leading to the
engine not running smooth. Therefore inorder to figure out where the claimed defect was, trials based upon shainin
technique was performed at the vehicle level initially by swapping of pumps and components between good & bad
vehicles. From these trials it was revealed that one particular component was being the potential root cause of the issue.
Hence inorder to rectify the issue with the component and to find the reason for the defects in them, various problem
solving techniques namely multi-vari analysis & Why Why analysis was brought into play. Thereby using these
techniques the area of the problem was found & corrective actions in consultation with the industry for reducing the
variability in the milling process of the machine were employed with an intent to bring down the defect rate & to put an
end to the existing real time customer issue.
