A design philosophy that ensures a system remains safe and reliable even when a user makes an operational error. The focus is on preventing mistakes from occurring in the first place through physical or logical mechanisms, such as confirmation dialogs before deletion or UI elements that block invalid actions. It differs from fail-safe design, which aims to minimize damage after a failure has already occurred.
