We often talk about safety as if organisations simply have clear purposes. We use slogans like Zero Harm, Safety First, or Everyone Gets Home Safe Today. But purposes aren’t stable objects, and they’re not fixed end states either. They’re certainly not timeless truths. Purposes are just temporary commitments people and organisations make to manage complexity together.

Traditional safety thinking treats individual actions as rational if they serve a purpose. But this overlooks that action only makes sense within a system. The system itself only exists through the ongoing flow of action, while it’s trying to maintain its identity in a constantly changing environment. This is why systems thinking matters; it helps us see how people, relationships and structures influence each other over time.

Multiple causes can lead to the same incident. The same cause can lead to different outcomes, depending on context. It’s an error to see causality as a property of the world. It’s rather a cognitive strategy for reducing complexity so we can act. Systems thinking accepts this and stops pretending investigations reveal the one-and-only truth.

Every decision touches production, cost, speed, convenience, and safety at once. A rigid value hierarchy such as ‘safety above all’ collapses under real operational conditions. Systems thinking acknowledges that organisations constantly neutralise some values to pursue others, then move back again as circumstances change.

Safety goals don’t describe a true future state. They help people focus attention, justify choices, and coordinate action over time. Systems thinking reframes purpose as a practical way of simplifying both causal options and value conflicts, so that organisations and the people in them can act.

When we see safety as something that emerges from the whole social system instead of just from slogans or individual behaviours, everything changes. Investigations become learning tools instead of blame hunts. Safety performance becomes about adaptation instead of just compliance. Leadership focuses on improving the system instead of correcting workers. Systems are time-sensitive. Priorities shift, conditions drift, and the system must continually recalibrate.

Systems thinking gives safety back its realism. Organisations survive by constantly reducing complexity instead of by discovering timeless truths. Systems thinking shows that people, practices and structures come together to make decisions, trade-offs and commitments; always in motion, always under changing pressures, just like that endlessly spinning clock.
