Design Review Documentation Strategies for FDA-Auditable Medical Electronics

Medical electronics is a highly regulated field, and design review documentation offers a structured approach to ensure that medical devices meet all required standards before reaching the market. In this article, I outline a comprehensive strategy for design review documentation, specifically focusing on Design Review in CFR21 part 820, and demonstrate how Altium 365 can facilitate this process.

Formal Design Reviews For Medical Electronics

According to 21 CFR 820.30(e), formal design reviews must be conducted at appropriate stages of the design process. These reviews are intended to assess the adequacy of the design and identify any potential issues.

The FDA requires that these formal reviews occur at key points in the development cycle, involving a multidisciplinary team that evaluates the design from multiple perspectives (including technical feasibility, regulatory compliance, and user needs).

The primary goal of design reviews is to ensure that the project is progressing as intended and that any issues are identified and resolved early. Regular reviews help organizations detect design flaws before they escalate, minimizing the risk of costly rework, delays, or even recalls.

Design reviews also serve as a critical checkpoint for verifying that the design aligns with regulatory standards and user expectations, ultimately contributing to a safer and more effective final product. Thorough documentation of each review is essential for demonstrating compliance with FDA requirements and maintaining a clear record of the decision-making process.

Altium 365 Design Review streamlines this process by offering a centralized platform for initiating, managing, and documenting PCB design reviews. It ensures traceability across all review activities and helps teams systematically capture and address feedback, enhancing both efficiency and regulatory readiness.
