• Discover design / process flaws early on in order to affect positive design changes for the least amount of investment
• Evaluate the effects of all hardware or functional failures on mission success, operating personnel and system performance
• Verify that no single point hazardous or catastrophic failure modes exist in the system or equipment
• Reduce sustaining and maintenance costs by positively impacting the reliability of the system
• Avoid costly field modifications
• Ensure safety and maximize profits

FMEA is often, especially in government programs, combined with criticality analysis (a.k.a. FMECA) in order to incorporate maintenance planning and logistics support analysis into the design and development process.  The FMECA also provides critical information required to support test planning, inspection and checkout requirements, and identifies maintainability design features that require corrective action, and supplies information for the Reliability-Centered Maintenance (RCM) process.  In addition, Parnassus has had good experience combining FMEA / FMECA with Testability analyses to accurately ascertain system fault detection and fault isolation capabilities.
