Safer by design, also written as safe-by-design or safer-by-design, is a design philosophy that safety considerations are integrated into the development of a product, system, or service from the earliest stages of conception. The aim is to reduce hazards and mitigate risks through design choices rather than relying solely on downstream safety features or corrective measures.

The approach encompasses systematic hazard identification and risk assessment, design for fail-safety and resilience, human factors engineering, and the use of verification and validation to demonstrate that safety requirements are met. It also often includes lifecycle thinking, continual risk monitoring, and documentation. In practice, it spans diverse domains such as chemicals, pharmaceuticals, medical devices, automotive, aerospace, software, and consumer electronics, with teams collaborating across engineering, safety, regulatory, and user-experience disciplines.

Safer by design is frequently guided by standards, codes, and frameworks that address risk management, functional safety, quality management, and regulatory compliance. Examples include general safety and quality standards, as well as domain-specific guidelines for medical devices, automotive systems, and industrial control. In AI and software, the concept is extended to include safety, security, and privacy considerations embedded into architecture and development processes.

Benefits of safer by design include reduced incident likelihood and severity, lower total costs over the product life cycle, earlier regulatory compliance, and increased user trust. Limitations include the need for cross-disciplinary expertise, upfront investment, and the challenge of defining and measuring safety outcomes in complex systems. It is not a substitute for ongoing monitoring and post-market surveillance.
