What is FMEA and FMECA
Things break. Systems fail. Sometimes it is just a coffee spill, other times it is a full-blown catastrophe. How do we find weak spots before they cause problems? That is where Failure Modes and Effects Analysis (FMEA) comes in. But what is FMEA?
FMEA is a method used to find and study possible failures in a system, product, or process. It looks at how something might fail, what happens if it does, and how likely it is to occur. Teams rate failures based on severity, frequency, and how easy they are to detect. This helps them focus on the most serious risks. FMEA is used in many fields, including aerospace, defence, healthcare, and manufacturing.
At Quorum, we have spent over 20 years solving complex engineering problems. Our Supportability consultants help clients manage risk and improve reliability in defence, energy, and transport projects. We know what works and what doesn’t. Keep reading to learn how FMEA compares to FMECA and why both matter.
FMEA Explained
FMEA stands for Failure Modes and Effects Analysis. It’s a way to find and study possible failures in a system, product, or process. It helps teams understand what could go wrong, how serious the problem would be, and how often it might happen.
The process starts by breaking down the system into parts. Each part is checked for ways it could fail. Every failure is then rated based on three things:
- Severity: How bad the impact would be if the failure happens
- Occurrence: How often the failure is likely to happen
- Detection: How easy it is to catch the failure before it causes harm
FMEA is used in many industries, from aerospace and defence to healthcare and manufacturing. Engineers, quality experts, and other specialists work together to spot risks early. This helps them decide where to focus their efforts to reduce failures and improve reliability.
What is FMECA
FMECA stands for Failure Modes, Effects, and Criticality Analysis. It builds on FMEA by adding a criticality assessment. This helps teams rank failures by risk, so they know which ones need attention first.
Like FMEA, FMECA starts by listing possible failures and their effects. But it goes further by measuring how likely each failure is and how much damage it could cause. This extra step helps teams focus on the most serious risks.
FMECA is common in defence, aerospace, and other high-risk industries. It helps ensure safety and reliability in complex systems. Many companies use it to meet strict industry standards and avoid costly failures.
7 Benefits of FMEA and FMECA?
FMEA and FMECA help teams find and fix risks before they cause problems. Key benefits include:
- Improved safety: Reduces the chance of dangerous failures
- Lower costs: Prevents expensive repairs, recalls, and downtime
- Better reliability: Helps products and systems last longer
- Regulatory compliance: Meets industry safety and quality standards
- Stronger risk management: Identifies and ranks potential failures
- Team collaboration: Brings experts together to solve problems.
- Data-driven decisions: Focuses resources on the most serious risks

FMEA and FMECA Steps
FMEA and FMECA follow a step-by-step process to find and rank risks. Here’s how it works:
- Define the scope: Decide what system, product, or process you will analyse
- List components or steps: Break it down into parts or actions
- Identify failure modes: Find possible ways each part could fail
- Describe effects: Explain what happens if the failure occurs
- Rate severity, occurrence, and detection: Score each failure to measure risk
- Calculate risk priority number (RPN) or criticality: Use the scores to rank failures
- Develop solutions: Plan fixes to reduce high-risk failures
- Review and update: Repeat the process as systems change or new risks appear
FMECA follows the same steps but adds a deeper risk ranking to focus on critical failures.
