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.
