FMEA

Failure Modes and Effects Analysis (FMEA) is a systematic, step-by-step approach for identifying all possible failures in a design, a manufacturing or assembly process, or a product or service. “Failure modes” refer to the ways, or modes, in which something might fail. Failures are any errors or defects, especially ones that affect the customer, and can be potential or actual.

FMEA is a structured, proactive method used in TQM to analyze potential failures in a product, process, or service. It’s essentially a way to brainstorm all the things that could go wrong and assess the impact those failures might have. By anticipating these issues, you can take steps to prevent them, saving time, money, and – most importantly – ensuring customer satisfaction.

The purpose of FMEA is to take action to eliminate or reduce failures, starting with the highest-priority ones. It provides a documented method for selecting a design with a high probability of successful operation and safety.

FMEA follows a systematic approach, typically involving a cross-functional team. Here’s a simplified breakdown of the process:
1. Define the System: Clearly identify the product, process, or service being analyzed.
2. Identify Potential Failures: Brainstorm all the ways things could go wrong within the system.
3. Analyze Effects: Consider the consequences of each failure mode on the customer or overall operations.
4. Rate Severity: Assign a score based on the seriousness of the potential outcome.
5. Rate Occurrence: Estimate the likelihood of each failure occurring.
6. Rate Detection: Evaluate how easily the failure would be identified before reaching the customer.
7. Calculate RPN (Risk Priority Number): Multiply the severity, occurrence, and detection ratings to prioritize risks.
8. Develop Actions: Based on the RPN, determine corrective actions to prevent or mitigate high-risk failures.
9. Document and Review: Document the findings and actions taken. Regularly review and update the FMEA as needed.
 

The Benefits of FMEA

By incorporating FMEA into your TQM strategy, you can reap several benefits:

• Proactive Problem Solving: Identify and address potential issues before they become real problems.

• Improved Quality: Reduce defects and improve overall product or service quality.

• Cost Savings: Prevent costly rework and recalls.
