Safety Cube Theory lays the foundation for proper systems integration through six fundamental aspects. Six essential views are represented by six faces of a cube, which we call the Safety Cube. Safety Cube theory formalizes the most fundamental elements of safe integration, emphasizing the seven pillars of secure integration. To summarise, these are: 1. the system under consideration (technical system or system); 2. the human who has a relationship or is associated with the system; 3. the operating environment or related environment of the system; 4. human-system integration; 5. system-environment integration; 6. human-environment interfaces that influence the system.
Safety Cube shows the six fundamental aspects of safe integration in the six faces of the Safety Cube. The figure on the leftside shows the three-dimensional visualization of the Safety Cube. The Safety Cube is an easy to grasp concept which visually supports system integration, not in isolation but as a part of the human or environmental context required for optimal integration. The Safety Cube involves knowledge in the disciplines of systems engineering, risk management, and safety engineering; prerequisites for safe and optimal integration.
