Maintainability Verification for Cost-Effective Execution

Maintainability verification is an essential component of system requirement verification that verifies the human-machine maintenance interface. Within maintainability design, agile acquisition and effective, efficient execution of the maintainability verification process is vital to the program schedule. A majority of verification is performed via test vehicle, or aircraft so, maintainability demonstration has a high impact on cost and schedule due to significant demonstration time on the vehicle and equipment. Consequently, this predicament causes maintainability requirements such as Mean Time To Repair (MTTR) to be verified by analysis of hardware design versus risking valuable flight, ground, or sea test time. Not performing a physical procedure on the test asset can also risk system validation.
