FMEA Alignment of AIAG & VDA Automotive suppliers to both North American and GermanOEMs were required to assess their failure modes andeffects differently Differences between the Severity, Occurrence, and Detection ratingtables in the AIAG and VDA FMEA Manuals Caused confusion and added complexity to productdevelopment and process improvement activities Alignment was needed in order to create a common set ofrequirements so suppliers can have a single FMEA businessprocess meeting needs and expectations of any of theirautomotive customers5888-336-1124 www.qualitysupportgroup.com 2019

Step 1: Planning & PreparationFive T’sQuestions to AnswerInTent Have all Core Team Members received training on FMEAs? Have all Core Team Members allocated time to fully participate?Timing What APQP Phase or VDA Maturity Level is the project in? What is the FMEA Start Date and Target Completion Date?Team Have the team members been assigned with clearly defined rolesand responsibilities (Leader, Facilitator, Champion, Core TeamMember, Extended Team Member)?Task Tools Will a spreadsheet or specific software program be used todocument the results?Is the scope of the study clear?Has the documentation/reporting methodology been clarified?Will the FMEA Report be shared with customers?Will the FMEA results be audited?9888-336-1124 www.qualitysupportgroup.com 2019
