Boundary & Parameter Diagrams in AIAG-VDA FMEA

Objective

Develop and apply Boundary and Parameter Diagrams as part of the AIAG/VDA 7-Step DFMEA methodology. Visualise system structure, interfaces and variation paths, and translate these insights into robust, measurable function statements that strengthen DFMEA quality and traceability.

Content

• Overview of AIAG/VDA 7-Step DFMEA
• Understanding the role of Boundary and Parameter Diagrams (Steps 2 & 3)
• Constructing Boundary Diagrams to define scope and interfaces
• Building Parameter Diagrams for variation and robustness analysis
• Linking diagrams to DFMEA function statements
• Case study: 12V Battery System
• Group exercise and review of diagram quality

Assessment

Participants will complete:

• A multiple-choice knowledge assessment
• Observation and output-based evaluations during practical sessions

Successful candidates will receive a Certificate of Competence.

Prerequisites

A basic understanding of DFMEA principles and the AIAG/VDA FMEA methodology is expected. Prior exposure to functions, failure modes and design documentation is beneficial.

Target Audience

• DFMEA Moderators
• Design, Quality and Process Engineers
• Product Development and Systems Engineers
• Advanced Practitioners of FMEA and Core Tools

Training Methodology

The course uses a combination of:

• Instructor-led presentations
• Interactive group discussions and feedback
• Group-based diagram construction and analysis
• Case study applications
