Objectives and Key Themes
The text aims to provide a comprehensive understanding of Failure Mode and Effects Analysis (FMEA), a method used to identify potential failures in products and processes during the development phase. It outlines the history of FMEA, its general facts and benefits, and its various types. The text also delves into the preparation of content for FMEA analysis, including structuring the product's components and identifying possible failures.
- History and development of FMEA
- Benefits and applications of FMEA in product and process development
- Types of FMEA including Design FMEA, Process FMEA, and System FMEA
- Methodology and steps involved in conducting FMEA
- Preparation of content for FMEA analysis, including product structure and failure identification
Chapter Summaries
The introduction delves into the history of FMEA, highlighting its origins in NASA projects and its subsequent standardization and adaptation for various industries. It also outlines the general facts and benefits of FMEA, emphasizing its role in identifying potential failures early in the development process. The text then explores various types of FMEA and provides a detailed description of the method, outlining the steps involved in conducting an FMEA analysis. The chapter on preparing the content for FMEA focuses on organizing the product's components into a structured graphic to facilitate the analysis. This chapter also introduces the concept of sublevels and provides examples of how to break down a product into its individual components.

Frequently Asked Questions
What is FMEA?
FMEA stands for Failure Mode and Effects Analysis. It is a systematic method for identifying potential failures in a product or process before they occur.
What are the benefits of conducting an FMEA?
The benefits include improved product quality, reduced development costs, early risk identification, and increased customer satisfaction.
What is the difference between Design and Process FMEA?
Design FMEA focuses on potential failures in a product's design, while Process FMEA focuses on failures within the manufacturing or assembly process.
What is an RPN in FMEA?
RPN stands for Risk Priority Number. It is calculated by multiplying Severity, Occurrence, and Detection rankings to prioritize which risks to address first.
How is a Pareto Analysis used with FMEA?
A Pareto Analysis helps to identify the "vital few" failure modes that contribute to the majority of the risk, allowing teams to focus their resources effectively.
