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)

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.
Product Support Analysis (PSA) primarily employs techniques such as Reliability Centered Maintenance (RCM), Failure Mode and Effects Analysis (FMEA), and logistics support analysis. RCM focuses on identifying the most effective maintenance strategies for critical components, while FMEA systematically evaluates potential failure modes and their impacts. Additionally, logistics support analysis ensures that necessary resources and support systems are in place to maintain product performance throughout its lifecycle. Together, these techniques enhance product reliability and optimize supportability.
In maintenance, diagnostic evidence is analyzed through systematic data collection and interpretation to identify the root causes of equipment failures or performance issues. Techniques such as trend analysis, failure mode and effects analysis (FMEA), and root cause analysis (RCA) are employed to evaluate the evidence. This analysis helps prioritize maintenance activities and informs decisions on corrective actions to prevent future failures, ultimately improving reliability and efficiency. The findings are often documented for continuous improvement and compliance purposes.

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.
