Juran, a recent hire in the quality department, was assigned the task of finding defective semi-conductor chips that were being manufactured at the rate of 1000 units per day. Juran discovered that nearly 15% of the chips were defective and thought that the defects were costly to the organization. Due to the high defect rate, Juran wanted to find the root-cause of the problem and eliminate it. He undertook an investigation and found that the defect was coming from the quality of sand that was being utilized for manufacturing the semiconductor. He also discovered that the sand was sourced from a supplier who was close to the manufacturer's location and was awarded the contract for convenience. He took up this issue with his manager, who suggested him to do his daily inspection task, as finding defectives was their department's task and eliminating the error was not their job.
