🔵 FMEA NA PRÁTICA - COMO MONTAR UM FMEA

Summary

In this video, the speaker introduces the concept of FMEA (Failure Mode and Effect Analysis), a crucial tool in product and process improvement. Originally developed in the aerospace and automotive sectors, FMEA helps identify potential failure modes and assess their impact based on three factors: occurrence probability, severity, and detection ability. The video provides a practical example, demonstrating how to evaluate different failure modes, calculate risk priority numbers (RPN), and prioritize actions to mitigate risks. The speaker emphasizes the importance of collaboration across departments to ensure comprehensive analysis and effective problem prevention.

Takeaways

• 😀 FMEA (Failure Modes and Effects Analysis) is a tool used to analyze potential failure modes in a product or process and assess their impact and probability.
• 😀 The FMEA process originated in the aerospace and automotive industries, where failure can be critical, and was popularized in the 1980s by the book 'The Machine that Changed the World'.
• 😀 FMEA evaluates three main factors: the probability of occurrence, the severity (or criticality) of the failure, and the ability to detect the failure before it reaches the customer.
• 😀 There are two types of FMEA: one for product development (design FMEA) and one for the manufacturing process (process FMEA).
• 😀 FMEA helps prevent product failures by identifying potential issues early and suggesting corrective actions to mitigate risks.
• 😀 The FMEA process involves a team approach, with input from different departments like quality, production, and product development to provide a comprehensive analysis.
• 😀 Using FMEA as a group activity promotes brainstorming and ensures a more thorough identification of potential failures across the entire process.
• 😀 The FMEA process is continuous and dynamic, meaning it is revisited regularly to ensure that new failure modes are identified as the product or process evolves.
• 😀 A key part of FMEA is assigning a score to each potential failure mode based on its severity, occurrence probability, and detection ability, known as the Risk Priority Number (RPN).
• 😀 Actions are recommended based on the RPN, with higher priority given to failure modes with higher RPN values. These actions aim to reduce the risk of failure and improve product quality.
• 😀 FMEA should not be used just for passing audits but as a proactive tool for improving product safety, quality, and reliability before reaching the customer.

Q & A

What does FMEA stand for?

FMEA stands for Failure Modes and Effects Analysis, a tool used to evaluate the potential failure modes of a product or process and assess their impact.

Why is it important to avoid confusing FMEA with 'fêmea'?

Fêmea, a common misspelling of FMEA, means 'female' in Portuguese, which could mislead potential employers or clients if seen on a resume, leading to confusion.

Where was FMEA first developed?

FMEA was initially developed in the aerospace industry, where failures could have catastrophic consequences, such as in rockets or airplanes.

How did FMEA become popular in other industries?

FMEA became popular in the automotive industry in 1989 after the publication of the book 'The Machine That Changed the World,' which discussed lean culture and the Toyota production system.

What are the three factors considered in FMEA?

The three factors are: the probability of occurrence, the severity of the failure, and the ability to detect the failure before it reaches the customer.

What is the difference between Design FMEA and Process FMEA?

Design FMEA focuses on product design and development, while Process FMEA assesses manufacturing processes to identify potential failures.

What role does severity play in FMEA?

Severity refers to how serious the consequences of a failure could be, such as injury, damage, or other critical issues that might arise from a product or process failure.

How is the probability of occurrence assessed in FMEA?

The probability of occurrence is assessed based on historical data, the process being used, and how likely the failure is to happen in a given scenario.

What is the significance of detection in FMEA?

Detection evaluates how easy it is to detect a failure before it affects the end user. A higher probability of detection results in a lower detection score, meaning it's easier to identify and prevent the failure.

What is the NPR (Risk Priority Number) and how is it calculated?

The Risk Priority Number (NPR) is calculated by multiplying the severity, occurrence, and detection scores. A higher NPR indicates a more critical issue that requires immediate attention and action.
