- Failure Mode and Effects Analysis (FMEA)
Failure Mode and Effects Analysis is a structured method for identifying how equipment or processes can fail, understanding the operational consequences of those failures, and determining the actions needed to reduce risk.
In maintenance and reliability, FMEA helps organizations move beyond generic preventive maintenance by connecting maintenance strategies to specific equipment failure modes and their consequences.
Implementation Engineers works directly with maintenance, reliability, engineering, and operations teams to conduct FMEA and, more importantly, translate the findings into executable asset strategies, preventive and predictive maintenance tasks, equipment maintenance plans, and reliability improvements.
The value of FMEA isn’t the analysis itself. It’s what you implement because of it.
What We Implement for Failure Mode and Effects Analysis
Asset Criticality & Prioritization
Focus reliability resources where failure creates the greatest business risk.
Before analyzing every possible failure, IE helps organizations determine which assets require the greatest attention based on factors such as production impact, safety, environmental consequences, quality, cost, and operational risk.
Asset criticality provides the foundation for prioritizing FMEA and reliability resources where they can create the greatest value.
Failure Mode Identification
Understand how and why critical equipment can fail.
IE facilitates cross-functional FMEA sessions with the people who understand the equipment, including maintenance, reliability, engineering, and operations.
Teams systematically identify potential failure modes, their causes and effects, existing controls, and the consequences of failure.
Operator involvement is particularly valuable because frontline teams often have practical knowledge of equipment behavior and recurring problems that isn’t captured in formal maintenance documentation.
This failure mode analysis helps teams connect equipment behavior with specific causes, effects, and required actions.
Risk Assessment & Prioritization
Determine which failure modes require action first.
Identified failure modes are evaluated based on risk criteria such as severity, occurrence, and detection. This allows teams to distinguish high-risk failure modes requiring intervention from lower-risk issues and prioritize reliability resources accordingly.
Maintenance Strategy Development
Convert failure analysis into maintenance action.
Once failure modes and risks are understood, IE determines the appropriate strategy for addressing them. Depending on the failure mode, this can include:
- Preventive maintenance
- Predictive or condition-based maintenance
- Operator inspections and care
- Planned replacement or restoration
- Equipment modifications
- Monitoring or inspection requirements
- Spare-parts requirements
- Run-to-failure strategies where appropriate
PM/PdM Optimization
Make sure maintenance tasks address actual failure modes.
One of the most important outputs of maintenance FMEA is determining whether existing preventive maintenance activities are actually preventing or detecting the failures that matter.
IE evaluates existing PM tasks against identified failure modes to identify gaps, unnecessary activities, ineffective frequencies, and opportunities for predictive or condition-based maintenance.
New or revised maintenance strategies can then be incorporated into the CMMS/EAM so they become part of the organization’s normal work management process.
Implementation & Sustainment
Move FMEA from a workshop into daily maintenance execution.
FMEA can easily become an engineering exercise that produces a spreadsheet but little operational change.
IE works with client teams to implement the resulting maintenance strategies, update CMMS/EAM requirements, establish equipment maintenance plans, train personnel, and integrate new reliability activities into planning, scheduling, operator care, and performance management.
Why Failure Mode and Effects Analysis Matters
Preventive Maintenance Isn’t Necessarily Effective Maintenance
A plant can have hundreds or thousands of preventive maintenance tasks and still experience recurring equipment failures.
Why?
Because performing more PM does not necessarily mean the right failure modes are being addressed.
FMEA creates a structured connection between:
Assets
Function
Potential Failure
Failure Mode
Consequence
Risk
Maintenance Strategy
This allows maintenance organizations to move away from calendar-based maintenance developed through historical practice and toward risk-based maintenance strategies designed around how equipment actually fails.
For critical assets, an equipment FMEA provides a structured way to identify failure modes and determine appropriate actions before failures affect production.
Frequently Asked Questions
What is FMEA in maintenance?
FMEA in maintenance is a structured approach for identifying how equipment can fail, why those failures can occur, what effects they may have, and what actions can reduce the risk. It helps maintenance teams develop targeted preventive, predictive, and condition-based maintenance strategies based on actual failure modes.
What is an FMEA risk priority number?
An FMEA risk priority number, or RPN, is a traditional method used to help prioritize failure modes based on factors such as severity, occurrence, and detection. The resulting score can help teams identify which failure modes need greater attention, although many modern FMEA approaches also consider risk directly rather than relying only on an RPN.
What is the difference between FMEA and RCM?
FMEA is a structured method to identify how equipment can fail, the consequences of those failures, and the actions needed to reduce risk.
RCM is a broader process that uses tools like FMEA to determine the most appropriate maintenance strategy (preventive, predictive, redesign, or run-to-failure) for each failure mode based on operational risk and consequences.
How often should an equipment FMEA be updated?
An equipment FMEA should be reviewed when there are significant changes to equipment, operating conditions, processes, maintenance strategies, or failure history. It should also be revisited when recurring failures or new failure information show that the existing analysis no longer reflects actual equipment performance.
