Safety Cube Theory

In short:

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 safe 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; and 7. Human-system-environment or the complete system integration.

Safety Cube shows the six fundamental aspects of safe integration in the six faces of the Safety Cube. The three-dimensional visualization of the Safety Cube is presented in Figure above. The Safety Cube can also capture both the hierarchical and behavioral aspects of integration. Its vertical and horizontal axes represent hierarchy and lifecycle (time), respectively. Furthermore, the hierarchical perspectives can be represented in the system or system-environment aspects, and the behavioral or operational perspective can be represented in the human-system and human-environment aspects. However, this requires further research. Nevertheless, 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 and/or environmental context required for optimal integration. The Safety Cube requires knowledge in the disciplines of systems engineering, risk management, and safety engineering; prerequisites for safe and optimal integration.
