The Current Situation - Reliability & Quality |
The US Military applies the Failure Mode, Effects and Criticality Analysis (FMECA) methodology to the acquisition of all designated Department of Defense systems and equipment. The standard used, MIL-STD-1629A, establishes the requirements and procedures for performing a FMECA to systematically evaluate and document the potential impact of each functional or hardware failure on mission success, personnel and system safety, system performance, maintainability, and maintenance requirements. Each potential failure is then ranked by the severity of its effect so that actions may be taken to eliminate or control the high-risk items.
MIL-STD-1629A primarily applies to the program activity phases of demonstration and validation and full-scale engineering development; e.g., design, research and development, and test and evaluation. It can also be used during production and deployment to analyze the final hardware design or any major modifications. The FMECA tasks contained in MIL-STD-1629A apply to all items of equipment, but not to software.
