FMEA is a systematic approach aimed at identifying and mitigating potential risks in the design, manufacture, and maintenance of a product. Implementing FMEA provides a range of benefits, such as: Preventing potential failures early in the life cycle. Identifying risk - establishing clear linkages ensures that no potential failure mode is overlooked across the life cycle of the product. Improving product safety, reliability, performance, and supportability. Enhancing collaboration - the framework fosters cross-functional communication, enabling design, manufacturing, and maintenance teams to work in harmony. Achieving effectiveness - by integrating analyses and plans, organizations can streamline workflows and reduce redundancies. Reducing costs associated with product failures. Enhancing customer satisfaction through consistent quality and reliability. Improving product quality - comprehensive linkage reduces errors and ensures a robust design and manufacturing process. Providing the basis for developing product support requirements through supportability analysis FMEA is versatile and shall be applied across various dimensions of product and process management. This standard provides terms, definitions, defined data elements, and essential information within each category of FMEA. The are many types of FMEA, but the primary types defined in this standard include: DFMEA: Focuses product design deficiencies during the design phase of a product and is updated based on product design changes throughout the life of the product design. SwFMEA: Addresses risks and issues specific to software during the design phase of a product and is updated based on software changes throughout the life of the product design. SupFMEA: Evaluates factors affecting product support and maintenance during the design phase of a product and is updated throughout the life of the product design. PFMEA: Concentrates on manufacturing and operational processes to identify and mitigate risks during the design phase of a product and is updated based on product or process changes throughout the life of the product design. Quantitative Criticality Analysis: Focuses on determining the risk of failure based on calculated or estimated failure rates. An essential part of the FMEA process is to identify and communicate potential issues that need to be addressed. When significant risks are discovered, it is incumbent on the FMEA team to communicate quickly to key stakeholders so that the project team can address as soon as feasible and not wait until the contracted deliverable is completed. FMEA is a dynamic and living process, the result of which is improved designs, manufacturing processes, and supportability, not forms or databases that are filled out. This standard applies to any product, process, or software in all phases of their life cycle. As a standard, this document contains requirements (“shall”) and recommendations (“should”) to guide the user through FMEA methods. There are many different Failure Mode and Effects Analysis (FMEA) and Failure Mode, Effects, and Criticality Analysis (FMECA) standards currently being used across many industries, but none of them constitute a complete, authoritative, and up-to-date resource for practitioners. This standard was created to establish a widespread practice for effective design, supportability, and process risk identification, assessment, mitigation, and prevention. This standard establishes contracting and performance requirements for the use of Design Failure Mode and Effects Analysis (DFMEAs), Software Failure Mode and Effects Analysis (SwFMEAs), Supportability Failure Mode and Effects Analysis (SupFMEAs), Process Flow Diagrams (PFDs), Process Failure Mode and Effects Analysis (PFMEAs), and Control Plans (CPs) throughout the product life cycle. It defines a methodology to mitigate risk using DFMEA, SwFMEA, SupFMEA, PFD, PFMEA, and CP. This standard also provides requirements for those organizations directed to complete Quantitative Criticality Analysis. The four types of FMEA covered in this standard are inclusive of other sub-types. For example, MIL-STD-1629A introduces two FMEA approaches, depending on variation in design complexity and available data: functional approach and hardware approach. In this standard, both of these approaches are included within the framework of Design FMEA. Other FMEA standards include System FMEA, which focuses on early design concepts, with emphasis on high-level functions and interfaces, and is also included within the framework of Design FMEA. This standard is intended to be used as a replacement for MIL-STD-1629A. Despite being cancelled in 1998, MIL-STD-1629A is still a key reference in the aerospace and Department of War (DoW) sectors. It has steadfastly guided engineering practices for over four decades. Yet, despite its extensive use and critical role, it has not been revised in more than 40 years. This standard recognizes the importance of MIL-STD-1629A, the need for its modernization, and the proposed approach to updating this standard to align with current industry’s best practices and technological advancements. The last four decades have witnessed significant technological advancements. New engineering tools and techniques have emerged, offering more efficient and accurate methods for conducting FMEA. However, these advancements are not reflected in the current version of MIL-STD-1629A. Starting with MIL-STD-1629A as a baseline, this standard incorporates these new tools and techniques essential for maintaining its relevance and effectiveness. While this standard is identified as an FMEA standard, it includes Criticality Analysis and therefore the process previously called FMECA. The terms FMEA and FMECA have caused confusion in the past, with some industries, such as defense, recognizing a difference between the two and others, such as automotive, including a Criticality Analysis element in FMEA. Criticality Analysis is an integral part of FMEA and is necessary to take full advantage of the benefits of FMEA. For clarity and consistency, this standard identifies FMEA as the overall process which includes criticality analysis. This standard was also developed to provide a common approach to meet the requirements of AS9145. Companies and organizations that use this standard shall meet the DFMEA, PFMEA, PFD, and Control Plan requirements of AS9145. AS9145 is a critical framework designed to enhance product quality and reliability within the aerospace and automotive industries and has been adopted by many other organizations and industries. This standard integrates Advanced Product Quality Planning (APQP) and Production Part Approval Process (PPAP) methodologies into a cohesive and systematic approach, ensuring that all products meet stringent aerospace and automotive requirements. Its purpose is to minimize risks, improve communication, and ensure that products are delivered on time and within budget. This standard establishes the timing to complete FMEAs within the product development process and requires continued updates as products, processes, and operations change throughout the product life cycle. This standard is focused on the usefulness of FMEA as a Design Tool and its role in the Decision-Making Process early in the product development process and maintaining configuration control throughout the life cycle of the product. FMEAs should be initiated as soon as the design or process concept is established. One of the key purposes of FMEA is the early identification of failure modes. By assessing potential failure modes during the preliminary design stages, designers can implement corrective actions before the system is fully developed. This proactive approach helps prevent costly redesigns and ensures that the final product meets reliability and safety standards. The standard also focuses on the usefulness of FMEA in the operational phases of the life cycle, providing recommendations for changes to design, processes, and support as operating experience is accrued.
