  • Ensure compliance with industry-specific certifications (such as ISO/TS 16949 for automotive or ISO 13485 for medical devices).

Quality Assurance Processes

  • Investigate the quality control measures they have in place. Regular inspections and detailed testing procedures can help mitigate risks of defects.
  • Understand their approach to handling product recalls or defects, which is crucial for maintaining product integrity.
