A Uniform Approach to Inspection Standards
Equipment used by U.S. Army soldiers must be ready at all times. Army mechanics and U.S. Department of Defense (DoD) contractors must maintain the Army’s automotive equipment to ensure it is “mission capable” when needed.

The standard left just enough wiggle room for each individual inspector to interpret the requirements in a manner that fits their concept of maintenance. This caused great diversity in actual maintenance standards. One quality management team at Fort Campbell, an Army base in Kentucky near the Tennessee border, sought to measure the cost of these varying interpretations and bring clarity to the application of the Army’s standard.

Chinese OEM Reduces Returns With Improved Product Testing (PDF, 184 KB)
When Continental Automotive Systems, Tianjin, China, began producing an electronic component known as the silver box, the return rate was more than 1,200 parts per million (ppm), versus a goal of less than 100 ppm. A Six Sigma improvement team used quality tools including trend charts, Pareto charts, and cause-and-effect diagrams to analyze the failure modes for the reported defects, finding that many were not being covered by product testing processes. A combination of technical innovation tools, including test coverage analysis, fault insertion, and a test methods selection matrix, along with Six Sigma process improvement and statistical tools, led the team to the solution of adding new testing items and a new testing station to the process. Adding the new tests reduced silver box returns to fewer than 50 ppm, producing cost savings of $130,000 per year while also strengthening relations with a major customer.
