Why “Human Error” Is Usually a System Design Problem
In complex systems, failure rarely comes from a single bad decision. It comes from problems that evolve slowly, cross boundaries, and remain unresolved while everyone involved behaves reasonably. Managing risk in these environments means managing trajectories, not just incidents. When ownership is divided strictly by role, function, or severity threshold, gaps are inevitable. Those gaps are where issues linger, age, and quietly accumulate risk, not because they were ignored, but because no one was responsible for carrying them forward end to end. This is common in healthcare, where delay is often necessary. A patient may require observation, referrals, or time to clarify diagnosis. The failure is not that care takes time; it is that the trajectory of care becomes fragmented. Each clinician escalates correctly within scope, yet no one owns the evolving picture across visits, domains, and decisions. The patient is evaluated repeatedly, reassured locally, and sent away without continuity ...
