Defining Functions & Requirements in FMEA

Last Updated: September 6, 2025

In Step 3: Function Analysis of the AIAG-VDA 7-Step FMEA approach, the first sub-step is defining functions and requirements. ๐Ÿ‘‰ This step answers two key questions: Defining functions and requirements properly is critical, because they form the foundation for identifying failures in Step 4 (Failure Analysis). What is a Function in FMEA? A function describes...

Step 3 โ€“ Function Analysis in FMEA

Last Updated: September 6, 2025

After completing Structure Analysis (Step 2), the next step in the AIAG-VDA 7-Step FMEA methodology is Function Analysis. ๐Ÿ‘‰ Function Analysis answers the question:โ€œWhat should each system, subsystem, component, or process step do, and how do they connect to each other?โ€ This step provides the link between structure and failure analysis by clearly defining functions...

Motor Stator Winding – Structure Analysis in FMEA Example

Last Updated: September 6, 2025

The AIAG-VDA 7-Step FMEA approach recommends starting with a structure analysis that breaks down a system into system โ†’ subsystem โ†’ component levels. To make this concept practical, letโ€™s consider an electric motor and analyze its breakdown into stator and winding, which are critical for motor function and reliability. ๐Ÿ‘‰ This example shows how Structure...

Process Flow – Structure Tree & Block Diagram in FMEA

Last Updated: September 6, 2025

In Step 2: Structure Analysis of the AIAG-VDA 7-Step FMEA approach, the team must visualize the system or process using diagrams. The three recommended tools are: ๐Ÿ‘‰ These diagrams bring clarity, alignment, and traceability before moving to Function Analysis (Step 3). 1. Process Flow Diagram (PFD) in FMEA The Process Flow Diagram shows how a...

System, Subsystem, and Component Breakdown in FMEA

Last Updated: September 6, 2025

A successful FMEA begins with a clear structure analysis. The AIAG-VDA 7-Step FMEA Handbook recommends breaking down the subject into System, Subsystem, and Component levels. ๐Ÿ‘‰ This hierarchical approach helps the FMEA team: What is System, Subsystem, and Component Breakdown? ๐Ÿ“Œ For PFMEA, this hierarchy applies as Process โ†’ Process Step โ†’ Work Element. Why...

Step 2 โ€“ Structure Analysis in FMEA

Last Updated: September 6, 2025

Once Step 1: Planning & Preparation is complete, the next step in the AIAG-VDA 7-Step FMEA approach is Structure Analysis. Structure Analysis provides a visual map of the system, subsystem, components, or process steps being analyzed. ๐Ÿ‘‰ It answers the question:โ€œHow is the product or process built, and how do its elements interact?โ€ Without a...

The Five Ts in FMEA – Intent, Timing, Team, Task, Tools

Last Updated: October 5, 2025

Before starting into detailed steps of an AIAG-VDA FMEA, it’s important to first understand the Five Ts – Intent, Timing, Team, Task, and Tools. These 5 elements work as the planning steps of any FMEA activity.  When you apply 5Ts correctly, then they align the entire team around the objective, scope, responsibilities, timing, and software,...

Cross-Functional Team Formation in FMEA

Last Updated: October 5, 2025

An FMEA (Failure Modes and Effects Analysis) is strong only when created by the strong team in FMEA. Why? Because risks exist in design, process, quality, maintenance, and customer use, no single person has expertise in all areas. Thatโ€™s why the AIAG-VDA 7-Step Approach tells us the formation of a cross-functional team (CFT) during Step...

Defining Scope, Boundaries & Assumptions in FMEA

Last Updated: October 5, 2025

Before jumping into failure modes, effects, and action priorities, thereโ€™s one crucial step you cannot skip in FMEA:Defining the Scope, Boundaries, and Assumptions. This step is important for: Without a well-defined scope and clear assumptions, your FMEA can be: In the AIAG-VDA 7-Step FMEA approach, this activity to be done in Step 1: Planning and...

Step 1 – Planning & Preparation in FMEA (AIAG-VDA Standard)

Last Updated: October 5, 2025

Failure Modes and Effects Analysis (FMEA) is not just a document creation activity. It is a disciplined risk analysis methodology, which starts with Step 1: Planning & Preparation. According to the AIAG-VDA FMEA Handbook, this step is the foundation for the entire FMEA process. Planning and preparation ensures that the analysis is structured, focused, and...
