Скачать или смотреть FMEA! FMEA Latest Edition!!How to fill FMEA New Format!!! (PART 1)

The AIAG & VDA FMEA manual is not a revision of the previous AIAG FMEA handbook. This manual is the product of a collaborative effort between automotive manufacturers, tier one suppliers along with members of AIAG (Automotive Industry Group) and the VDA (Verband der Automobilindustrie) which is the German association for automotive manufacturers. The AIAG & VDA manual is intended as a replacement for both the AIAG 4th edition FMEA handbook and the VDA Product and Process FMEA volume 4 manual

The FMEA Seven Step Approach

The new AIAG & VDA FMEA manual introduces a seven-step systemic approach that views the resulting FMEA as a record of the technical analysis. While reviewing the seven steps you will discover that included within many of the steps are tools that we have been employing for robust FMEA development for years. These tools are now imbedded into the seven-step methodology. In addition, the manual encourages organizations to develop foundation FMEAs upon which to build a robust Design and Process risk analysis process. Furthermore, the seven-step approach also includes some new content and a new approach to evaluating and managing recommended actions among other changes. The seven-step approach is as follows:

Step One – Planning and Preparation

The new manual includes valuable detailed information regarding topics that should be reviewed and considered early in project planning phase prior to any FMEA activities. The purpose of this discussion is to ensure that you achieve the best results and benefit from the FMEA. The planning stage generally includes determining the scope of the project, the type of FMEAs to be completed (Concept, System, Sub-system, Component, etc.), setting the boundaries of the FMEA analysis and defining the basis for the structural analysis step. The 5Ts of FMEA development must also be taken into consideration during the planning and preparation step. The following is a list of the 5Ts along with a brief description of each topic.

FMEA – InTent

Ensure that the team members are competent to participate in the FMEA based on their experience and role in the FMEA development process. More importantly they should understand the purpose of the FMEA.

FMEA –Timing

In order to gain the most benefit from the FMEA, it should be a “before – the – event” process and not an “after – the – fact” exercise. It is much easier to make changes to a design or process prior to design completion or process implementation.

FMEA – Team

The FMEA team should include members from different disciplines who have the subject matter knowledge and experience to obtain the greatest benefit. The AIAG & VDA manual provides a great deal of information and insight regarding the team members and their various roles and responsibilities.

FMEA – Task

The seven-step process outlined in the manual clearly identify the tasks and deliverables at each phase of the FMEA development. The team should also be prepared to share information with management at various times during the process.

FMEA – Tools

There are many different software tools on the market that can be used for FMEA development. In some cases, organizations develop their own internal software. In addition, there is always the traditional form-based exercise utilizing the standard spreadsheet method. The manual provides an example of both a software and a spreadsheet developed FMEA.

Step Two – Structure Analysis

During the structure analysis step in the FMEA process, the team should identify the boundaries of the design or process being analyzed and define the scope of the analysis to determine which systems, sub-systems, and or components will be part of the FMEA analysis. The interfaces and interaction of the items within scope must also be addressed. Tools that are useful in analyzing the structure, interactions and scope of the FMEA analysis are the Boundary or Block Diagram and the Structure Tree.

Step Three – Function Analysis

The functions specified by the design functions are allocated to the system elements during this step in the process, the inputs interfaces and outputs of the function or system are also reviewed. The tools useful in this step of the process are the P-diagram, and Function tree. The internal and external customer requirements should be included. The team should also review the association of certain design features or requirements to the functional requirements.

Step Four – Failure Analysis

The product potential failure modes, effects and possible causes are developed and reviewed during this step in the process.  A failure mode can be defined as “The method in which a product or process could fail to meet requirements or perform the desired function. The new standard also includes information describing the “Failure Chain”. The failure chain is best explained as the
