Summary

A Design Transfer Report documents the completion and results of design transfer activities, providing evidence that your medical device design has been successfully transferred from development to manufacturing. This report demonstrates that manufacturing processes can consistently produce devices conforming to validated design specifications and regulatory requirements.

Why is Design Transfer Report important?

The Design Transfer Report serves as critical documentation proving that your manufacturing process accurately reflects the validated design and can consistently produce compliant medical devices. Regulatory authorities require this evidence to verify that design controls were properly maintained during the transition to manufacturing. Without a comprehensive transfer report, you cannot demonstrate that manufactured devices will perform as intended or meet the safety and effectiveness requirements established during design validation.

Regulatory Context

Under 21 CFR Part 820 (Quality System Regulation):

  • Design transfer documentation is required under Section 820.30(h)
  • Must provide objective evidence that design outputs were correctly translated
  • Transfer results must be documented and verified before commercial distribution
  • Required for Design History File completeness (820.30)
  • Must demonstrate manufacturing capability to produce conforming devices

Special attention required for:

  • Complete verification of manufacturing process capability
  • Documentation of all transfer verification activities
  • Evidence of personnel training and qualification completion
  • Integration with overall design control documentation

Guide

Your Design Transfer Report should comprehensively document the execution and results of design transfer activities, demonstrating successful transition from design to manufacturing.

Example

Scenario

You have completed design transfer for your mobile cardiac monitoring application to your software development and distribution partner. The transfer included establishing automated build processes, quality control procedures, and distribution systems. You need to document the transfer results and confirm readiness for commercial software manufacturing.
