Problem Statement During the period Jan – Dec 1999, $29,407 Scrap/Rework costs were incurred as a result of Office related problems. Of this $20,799 were caused by Electrical Design faults, of which fault code 61E (Quality Improvement Notes – Connection Error) accounted for $9,973. This is % of all ELD faults and % of all Office related errors. . Problem Objective Reduce Scrap/Rework costs attributed to fault code 61E by 50% by 31st May 20xx yielding direct savings of $5,000 . . Project selection and Pareto Analysis This project was selected because there was perceived to be an increasing amount of time spent on rework by the Winding Department due to incorrect connections being specified on orders. Historical data was collected over a period from January 1999 to December 1999 in the form of Quality Improvement Notes. Analysis of the data was done using Pareto Charts in order to determine the main aspects of the problem that impact most on the business in relation to scrap and rework. 5 . First Level Pareto Analysis The first level Pareto Chart above shows that Electrical Design was the source of approximately two thirds of all Main Office related errors, and the second level Pareto Chart below shows that fault code 61E was the largest single error of all Main Office errors. Both of these Pareto Charts are shown by the value of scrap and rework. Fault code 61E relates to incorrect connection errors on the Quality Improvement Notes.

The Paretos show quite conclusively that winding diagrams cause the most concern on both hand and veser windings. This would appear to ply with the fact that most of the special windings are produced by one of these winding methods. Note that the period covered by the data in these last two Pareto Charts is from January 1999 to March 1999.
