Failure analysis in maintenance management involves systematically investigating equipment failures to identify root causes and prevent recurrence. By analyzing failure data, organizations can implement predictive and preventive maintenance strategies, improving reliability and reducing downtime. This approach enhances decision-making regarding resource allocation and maintenance scheduling, ultimately leading to increased efficiency and cost savings. Additionally, failure analysis fosters a culture of continuous improvement, allowing teams to learn from past mistakes and optimize maintenance processes.
Reliability Centered Maintenance (RCM)
preventive maintenance
The old concept of maintenance was to attend a machine after it has failed or stopped functioning. But now some more concepts have been identified and applied in the realm of MAINTENANCE. It is no more ' work after failure". According to author of one article, the following are the basics types of maintenance programs. 1) Reactive maintenance or corrective maintenance or Break down maintenance 2) Preventive maintenance 3) Predictive maintenance 4) Proactive maintenance The author gave sufficient details of each of above types in said article. See Sources and Related Links for more information. Ter-technology is economic management of assets. Maintenance is a part of tero-technology.

Product Support Analysis (PSA) primarily employs techniques such as Reliability Centered Maintenance (RCM), Failure Modes and Effects Analysis (FMEA), and Maintainability Analysis. RCM focuses on optimizing maintenance strategies based on the reliability of components, while FMEA systematically identifies potential failure modes and their impacts. Additionally, Maintainability Analysis assesses how easily a product can be maintained, ensuring efficient support throughout its lifecycle. Together, these techniques help enhance product reliability and reduce lifecycle costs.
FTA (Fault Tree Analysis) and FMEA (Failure Mode and Effects Analysis) are two methodologies used in risk analysis. FTA focuses on identifying potential failures in a system and analyzing how they can lead to a specific outcome, while FMEA looks at individual failure modes and their effects on the system as a whole. FTA is more focused on the overall system failure, while FMEA is more detailed in analyzing specific failure modes. The impact on the overall risk management process is that FTA helps in understanding the system-level risks, while FMEA helps in identifying and mitigating specific failure modes, leading to a more comprehensive risk management approach.

Equipment Failure Mode and Effect Analysis (EFMEA) is a systematic technique used to identify and prioritize potential failure modes of equipment, understand their causes and effects, and develop preventive actions to mitigate the risks associated with those failures. It is commonly used in industries such as manufacturing, aviation, and healthcare to improve equipment reliability, maintenance strategies, and overall system performance.
Failure mode effects analysis (FMEA) is used to identify the ways in which a system will fail, the likelihood of each failure mode, and what will happen in the event of each failure. It is used in both product design, to improve intrinsic availability and reliability, and in operations management, to improve process design.
The names of some management tool software programs are 5 whys, analysis of variance, ANOVA Gauage R&R, Axiomatic design, Business process mapping, Check sheet, control chart, correlation, cost benefit analysis, CTQ tree, design of experiments, failure mode and effects analysis.
The product support analysis tool commonly used to examine and classify failures in acquisition systems is the Failure Mode and Effects Analysis (FMEA). FMEA systematically identifies potential failure modes, assesses their impact on system performance, and prioritizes them based on severity, occurrence, and detection. This tool helps in understanding how each failure affects the overall system, facilitating risk management and informed decision-making in product support and design improvements.
The acronym DFMEA stands for "Design Failure Mode Effects Analysis". DFMEA is an extension of Failure Mode and Effects Analysis which attempts to estimate the frequency and severity of each failure mode.
