5T Method

The AIAG & VDA manual covers five topics (5T) that must be identified before working with FMEA risk analysis.

It is mandatory for companies that work in accordance with the requirements set out in the AIAG & VDA manual, but it is also worth implementing it when these requirements do not apply to us.

The 5T consists of:

1. InTent – Purpose

Why are we doing FMEA??

The purpose of the FMEA analysis that we are going to perform should be precisely defined.

  • What is it about?
  • Is it a new project?
  • Is it an update to an existing analysis?

Additionally, it is worth taking care of the appropriate preparation of the team so that each member knows how to work with the FMEA method.

2. Timing 

Until when do we need to carry out the FMEA analysis?

FMEA analysis should not be done at the last minute. Work should start early enough so that the FMEA does not lose its preventive form. The AIAG & VDA Handbook interferes with the traditional APQP approach, according to which DFMEA started in Phase Two and was later the “entry” to PFMEA initiated in Phase Three, imposing the initiation of DFMEA and PFMEA in Phase One APQP.

3. Team 

Who should work on FMEA?

The new manual clearly defines the composition of the FMEA teams, which should guide the organization in determining the mandatory composition of the team.

The role of the moderator is emphasized, who is to be responsible for the course of the analysis and for the work of the team. The handbook defines as many as 14 competences of an ideal moderator.

4. Tasks 

What tasks do you need to complete?

At this stage, the moderator should discuss with the team the course of work, its individual stages (7 steps), expected results, so that the team is also prepared to discuss the results with the management, client and auditor.

5. Tools

How do we conduct the analysis?

It is about choosing the right FMEA analysis tool, i.e. software. It should be ensured that each team member is able to operate the program and correctly perform the FMEA analysis in it. Although there is no ban on working on spreadsheets, it is ineffective, especially for large projects.
