Systems-Theoretic Process Analysis

STPA is a hazard analysis methodology for socio-technologic systems based on systems thinking with modeling of accident causation. STPA, a relatively new methodology centered on systems theory rather than reliability, is used to depict hazardous scenarios and the context that produces the scenario. By knowing the conditions for creating a possible hazardous scenario, measures can be created to eliminate, reduce, and control the scenarios in system design, development, manufacturing, and operations. STPA has achieved a reputation for identification of more casual factors and hazardous scenarios than traditional methods, particularly those related to software, system design, and human behaviors.

The RM Studio – STPA tool provides users with the necessary features, functions and reporting to properly complete the STPA:

  • Diagramming canvas and tools utilized to design and capture Hierarchical Control Structure (HCS), hazards – losses relationship, and Loss Scenarios Modeling;
  • Automation throughout the STPA tool, specifically analyzing Unsafe Control Actions and Loss Scenarios with the data from the control structure
  • Relationship linking of hazards to losses and constraints
  • Progress and consistency checking of the analysis process with a meter automatically measuring completeness of the analysis for each step: HCS, UCAs, & Loss Scenarios.
  • Report generation (full or by section) and data export including models and diagrams;
  • Information traceability throughout the system.
