Abstract: An industry makes fuel injection pumps for tractor engines. Recently it was observed that the fuel injection pumps were making too much noise in the engines. The problem-solving techniques of industrial engineering were used to solve this problem. One such simple but powerful problem-solving technique is the ‘is and is-not’ approach. This technique was used to identify the root cause of the increased noise of the fuel injection pumps. Once the cause was identified, the problem was rectified. Thus the industry was able to reduce the noise of the fuel injection pumps.
