Safety Cube 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 below 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 from 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.
