At what stage does the safety program begin according to systems engineering principles?

The safety program begins in the conceptual stage because this is when initial safety requirements are established and integrated into system design. During this phase, it's crucial to identify potential hazards and risks associated with the system to ensure that they are effectively addressed throughout the project lifecycle. By incorporating safety considerations early, systems engineers can develop strategies to mitigate risks, comply with relevant safety standards, and create a solid foundation for future stages of the project.

Starting the safety program in the conceptual stage allows for the thorough analysis of design alternatives and their safety implications, ensuring that safety is not merely an afterthought but a fundamental aspect of the system's architecture. Engaging with safety at this early point also enhances stakeholder confidence and prepares the team for subsequent phases, such as development and production, where implementing safety measures becomes increasingly complex and costly.
