FMEA, i.e., “Failure Mode and Effects Analysis,” is a risk-analysis method widely used in both manufacturing and service sectors that systematically evaluates potential failure modes and their effects.
Thanks to FMEA analysis, possible failures are identified before they occur, and preventive measures are taken. In this article, we'll examine in detail FMEA's importance in the business world, its application steps, its types and how it adds value with real-life examples.
You'll also find comprehensive answers to frequently asked questions such as FMEA risk analysis, what APQP is, a risk-analysis example and what the types of FMEA are.
What Is FMEA? Basic Concepts and the FMEA Acronym
FMEA is the abbreviation of the English phrase “Failure Mode and Effects Analysis.” Its main purpose is to identify the potential failure types that can occur in a product, process or system, to analyze the possible effects of these failures and to prioritize them.
FMEA analysis was first developed in the aviation and defense industry in the 1940s and later became widespread in many areas such as the automotive, healthcare, energy and service sectors. It is especially considered an inseparable part of APQP (Advanced Product Quality Planning) processes in the automotive sector. Since not all problems are equally important, FMEA is important for determining problem priority. For FMEA not to remain a static exercise, it must be continuously corrective and improving.
The FMEA Acronym and Definition
- F (Failure): A failure, fault or breakdown situation
- M (Mode): The way the failure occurs
- E (Effects): The effects of the failure on the system or customer
- A (Analysis): The analysis, evaluation and prioritization process
The main purpose of FMEA is to identify risks in advance and minimize these risks with preventive actions.
Why Is FMEA Important?
FMEA risk analysis enables companies to reduce financial and operational losses by anticipating potential problems they may face.
Would you like to know why FMEA is so important in the business world? Here are some key points:
- Proactive Risk Management: Thanks to FMEA, possible failures are detected and prevented before they occur.
- Cost Savings: Early detection of errors is achieved thanks to FMEA, so correction costs and warranty expenses decrease.
- Customer Satisfaction: The quality product and service delivery resulting from FMEA lowers customer complaints and return rates.
- Compliance with Laws and Standards: FMEA is a mandatory or recommended tool in quality management systems such as ISO 9001 and IATF 16949.
- Continuous Improvement: FMEA contributes to the continuous improvement of processes and products.
According to eMaint's current data, FMEA helps companies run safer and more efficient operations by identifying potential failure modes both in product design and process management.
What Are the Types of FMEA?
FMEA analysis is divided into different types according to the application area. Each of these types is specially designed to evaluate the risks of a specific process or product. Now let's examine the main types of FMEA:
Design FMEA (DFMEA)
DFMEA is applied at the design stage of the product. Here, the aim is to analyze the potential failure modes that can arise from the design and the effects of these failures on the customer.
For example, the possible faults in the design of a car's braking system and their effects on road safety are evaluated.
Process FMEA (PFMEA)
PFMEA is applied in production or service processes. In this type, the errors that can occur in the process steps and their effects on production quality are analyzed.
For example, errors such as incorrect part assembly or missing screw use on an assembly line are detected with PFMEA.
System FMEA
System FMEA is applied in complex systems consisting of more than one component. The failure modes across the system and their effects on one another are analyzed.
Other Types of FMEA
- Service FMEA: Analyzes potential errors in service processes.
- Software FMEA: Examines failure modes in software development processes.

How Is an FMEA Analysis Done?
FMEA analysis can be defined as a living process. For this reason, this process must be tracked regularly. It is possible to summarize the steps of this systematic, step-by-step process as follows:
1. Forming a Team and Defining the Process
- First, an interdisciplinary team that knows the subject is formed.
- The product, process or system to be analyzed is defined in detail.
2. Identifying Potential Failure Modes
- The failure types that can occur at each step or component are carefully listed.
- Failure modes are determined with past data, customer complaints and expert opinions.
3. Analyzing the Effects and Causes of Failures
- The effects of each failure mode on the system, customer or process are evaluated.
- The causes of the failure occurring are analyzed.
4. Calculating the Risk Priority Number (RPN)
- In general, each failure should be scored on three basic criteria:
Severity (S): The seriousness of the failure's effect
Occurrence (O): The probability of the failure occurring
Detectability (D): The ease of detecting the failure
- The risk priority number is calculated with the formula RPN = S x O x D.
5. Planning Preventive and Corrective Actions
- In the next step of FMEA, preventive and corrective actions are determined for failure modes with a high RPN value.
- The owners and completion dates of the actions are assigned.
6. Monitoring and Updating
- The effectiveness of the actions is monitored, and new measures are taken if necessary.
- The FMEA document is updated regularly.
An FMEA Risk Analysis Example
Let's clarify the topic a bit more with an FMEA risk analysis example. In an automotive part production process, the risk of incorrect part assembly was identified. The severity score was determined as 8, the occurrence as 5 and the detectability as 4. RPN = 8 x 5 x 4 = 160.
For this high-risk error, an automatic control system was added to the assembly line, and the risk was thus reduced.
The Relationship Between FMEA and APQP
The answer to the question of what APQP is will help us better understand FMEA's place in the business world.
APQP (Advanced Product Quality Planning) is an approach used especially in the automotive sector that aims to systematically plan product and process quality. FMEA is a critical step of APQP and ensures that risks are managed at every stage of the product-development process.
It is possible to summarize FMEA's role in the APQP process as follows:
- Early detection of risks in the product- and process-development stages
- Meeting customer requirements
- Achieving quality goals

Case Study: FMEA in the Healthcare Sector
In a hospital, an FMEA analysis was conducted on the medication administration process. The situation of giving medication in the wrong dose was identified as a potential error.
For this error with a high severity score, a “barcoded medication tracking system” was put into operation, and the risk was significantly reduced.
The Advantages and Disadvantages of FMEA
FMEA is an error-detection method frequently used in business life. It is possible to summarize the advantages of this analysis method as follows:
- Early detection of risks is achieved with a proactive approach.
- A culture of continuous improvement is supported.
- Cost and time savings are achieved.
- Customer satisfaction is increased.
That said, FMEA also has disadvantages for companies and leaders:
- The application process can be time-consuming.
