Software Development for Regulated Digital Health
Developing digital health products requires more than strong engineering. Software that performs medical functions must be built within a controlled development environment that supports safety, traceability, and regulatory accountability. Development practices must demonstrate that the software was designed, implemented, verified, and maintained in accordance with recognized medical device standards.
Frelong Health supports organizations developing regulated digital health systems by helping align software engineering practices with regulatory expectations. Our work focuses on building development environments that allow engineering teams to move efficiently while maintaining the documentation, lifecycle control, and traceability required for regulatory review.
Regulated Software Development Lifecycle (SDLC)
We assist teams in establishing software development lifecycles that integrate regulatory requirements directly into engineering workflows. This includes aligning development practices with standards such as IEC 62304 and ISO 13485, ensuring that requirements management, configuration control, verification planning, and release management operate as part of a structured quality system.
The objective is to create a development environment where regulatory compliance is built into the lifecycle rather than imposed after development has already occurred.
Requirements & System Architecture
Clear system architecture and well-structured requirements are foundational to safe and effective digital health products. Frelong Health helps organizations define system boundaries, develop structured requirements, and establish traceability between system requirements, software requirements, risk controls, and verification activities.
These practices help ensure that the intended clinical functionality of the product is clearly documented and that design decisions can be justified during regulatory review.
Risk Management Integration
Risk management is central to regulated software development. We help organizations integrate risk management activities into the development lifecycle in alignment with ISO 14971, ensuring that identified hazards, risk controls, and residual risk evaluations are consistently reflected in requirements, testing activities, and lifecycle documentation.
This integration allows development teams to maintain continuous awareness of safety considerations throughout the product lifecycle.
Traceability & Documentation Architecture
Regulators expect manufacturers to demonstrate clear traceability between requirements, design outputs, verification activities, and risk controls. Frelong Health assists teams in building documentation structures that support this traceability while remaining practical for engineering teams to maintain.
This includes designing traceability frameworks that connect system requirements, software requirements, risk management artifacts, and verification evidence into a coherent and defensible documentation structure.
Release & Lifecycle Governance
Regulated software must remain under control throughout its lifecycle. Frelong Health helps organizations establish processes for software release management, change control, configuration management, and post-release monitoring.
These processes support controlled product evolution while maintaining regulatory compliance as the software continues to develop and expand in the field.
Practical Engineering Support
Beyond documentation and process design, Frelong Health also works directly with engineering teams to ensure that regulatory expectations align with real-world development practices. This includes guidance on development tooling, documentation workflows, and verification strategies that support both engineering productivity and regulatory defensibility.
Result
The outcome is a development environment where engineering teams can continue building innovative digital health solutions while maintaining the structure, traceability, and lifecycle control necessary to support regulatory submissions and long-term product governance.
Frequently Asked Questions
Common questions about regulated software development, IEC 62304, ISO 13485, and AI-enabled digital health systems.
-
Regulated software development in digital health refers to building software under structured quality and lifecycle controls aligned with standards such as IEC 62304 and ISO 13485. This ensures traceability, risk management, and verification activities are documented and defensible for regulatory review, particularly for Software as a Medical Device (SaMD).
-
IEC 62304 defines the software lifecycle requirements for medical device software, including planning, development, testing, and maintenance. It ensures that software is developed in a controlled, risk-based manner with clear traceability between requirements, risk controls, and verification activities.
-
ISO 13485 provides the quality management system (QMS) framework that governs how software is developed, documented, and maintained. It ensures processes such as design controls, document control, CAPA, and supplier management support compliant and consistent software development practices.
-
Traceability is the ability to link system requirements, software requirements, risk controls, and verification results throughout the development lifecycle. Regulators expect end-to-end traceability to demonstrate that all risks are controlled and all requirements are properly verified.
-
Risk management, typically aligned with ISO 14971, is integrated directly into the development lifecycle by linking hazards to requirements, risk controls, and testing activities. This ensures that safety considerations are continuously addressed from design through validation and post-market monitoring.
-
Yes, AI can be used to accelerate documentation, testing, and analysis, but it must be applied within a controlled and compliant framework. Human oversight, validation, and traceability remain essential to ensure that AI-supported processes meet regulatory and ethical expectations.

Plan it.
Compliant software starts with the right foundation. We align your project with ISO 13485, ISO 14971, and IEC 62304 to ensure that requirements, risk management, and documentation are built into the process from day one. Whether you’re developing SaMD, SiMD, or AI/ML solutions, we help you plan for compliance from the very beginning.
-
Build it.
Our team supports every stage of the software lifecycle — from design and development to verification and validation. With an audit-ready Quality Management System (QMS) available to contract clients, we provide the structure and documentation you need to satisfy regulators and move forward with confidence.
-
Prove it.
Compliance isn’t complete until your software can stand up to review. We prepare the Design History File (DHF), traceability matrices, and supporting documentation that ensure your project is ready for FDA, notified body, or internal audits. The result: software that is not only innovative but also defensible, reliable, and regulatory-ready.
