Step-by-Step Guide: Writing a Software Requirements Specification (SRS) for FDA 510(k) Submissions

  • by

If you’re developing a medical device with software components, one of the most critical documents for your FDA 510(k) submission is the Software Requirements Specification (SRS). This document serves as a foundation for your entire software development lifecycle, ensuring regulatory compliance and software quality.

In my latest YouTube video, I provide a step-by-step guide on how to write an effective SRS tailored for 510(k) submissions. Watch the video here: [How to write FDA 510k SRS]

Why is the SRS Important for 510(k)?

The FDA’s guidance on software documentation requires an SRS to outline the functional and non-functional requirements of your software. It helps in risk management, verification and validation (V&V), and overall compliance with IEC 62304 and FDA’s expectations for software in medical devices.

Key Components of an SRS for FDA 510(k) Submission

  1. Introduction
    • Purpose and Scope
    • Intended Use and Indications for Use
    • Regulatory and Compliance Considerations
  2. Overall System Description
    • System Overview
    • User Characteristics
    • Assumptions and Dependencies
  3. Software Functional Requirements
    • Detailed feature descriptions
    • Input and output specifications
    • System workflows
  4. Non-Functional Requirements
    • Performance constraints
    • Security and cybersecurity considerations (e.g., FDA’s premarket cybersecurity guidance)
    • Reliability and maintainability
  5. External Interfaces
    • Hardware, software, and network interfaces
    • Communication protocols
  6. Risk Management & Mitigations
    • Integration with the Risk Management File (per ISO 14971)
    • Traceability to hazard analysis
  7. Verification & Validation Considerations
    • Requirements traceability matrix (RTM)
    • Testing methodologies

Common Pitfalls in SRS Documentation

  • Lack of clarity – Requirements should be clear, testable, and unambiguous.
  • Missing cybersecurity considerations – The FDA now expects robust cybersecurity measures in your SRS.
  • Ignoring risk management – All requirements should be linked to potential hazards and mitigations.
