A structured process framework that sequences safety-relevant activities across the stages of a system's existence — conception, design, implementation, operation, maintenance, and decommissioning — so that hazards are identified, risks are assessed and treated, and safety performance is verified and reviewed at each stage. Its parameters are the stage boundary (which defines which safety activities apply), the feedback loop (which carries lessons from operation back to design), and the governance checkpoint (which authorizes progression to the next stage). It persists through documented procedures, standardized templates, and regulatory or organizational mandates that require compliance audits.

Definition
Why it is in scope
A human-made process framework that structures safety activities across the stages of a system's existence — from conception through design, operation, maintenance, and decommissioning. It is built to persist as a discipline of systematic risk management across engineering, operational, and organizational contexts.

The safety lifecycle is designed for the sake of safety management: it structures and sequences all safety-relevant activities so that safety management can systematically address hazards across the full system existence.

A safety lifecycle is a specific kind of process — a structured sequence of safety-relevant activities from concept through disposal. Law 9: specific→general. The safety lifecycle follows a defined process framework (e.g. IEC 61508). A competent speaker would call a safety lifecycle 'a process'.
