felaktigsäker

Felaktigsäkerhet, often referred to as "felaktigsäker," is a concept within the field of human-computer interaction and design that emphasizes the prevention of user errors by making it impossible for users to perform incorrect actions. The term originates from the Swedish phrase *felaktig*, meaning "incorrect," and *säker*, meaning "safe." This principle is closely related to the broader idea of usability and safety in system design, particularly in contexts where mistakes could lead to serious consequences, such as medical equipment, industrial machinery, or transportation systems.

The core idea behind felaktigsäkerhet is to eliminate or mitigate human error through design choices that constrain user actions. This is often achieved by removing or hiding dangerous options, requiring explicit confirmation for critical actions, or structuring interfaces in ways that guide users toward correct behavior. For example, a medical device might disable a lethal dose setting unless a secondary authentication step is completed, ensuring that accidental activation is impossible.

Felaktigsäkerhet differs from traditional error prevention methods, which may rely on warnings or instructions, by focusing on eliminating the possibility of error rather than relying on user vigilance. This approach is particularly valuable in high-stakes environments where reliability is critical. The concept aligns with Jakob Nielsen’s usability heuristics, specifically the principle of *error prevention*, which advocates for designing systems that minimize the likelihood of mistakes.

While felaktigsäkerhet is highly effective, it can sometimes lead to overly restrictive designs that limit flexibility. Designers must balance strict safety measures with usability to ensure that systems remain functional and intuitive. The principle is widely applied in industries such as aviation, healthcare, and automotive engineering, where even minor errors can have significant repercussions. By integrating felaktigsäkerhet into design processes, developers can create safer, more reliable systems that reduce the risk of human error.
