 | Support for STPA steps 1-4:Supports the full range of steps in STPA: defining losses & hazards, constructing the control structure, conducting UCA analysis, and drafting loss scenarios. |
 | Computerized Control-Structure:Instead of using a visual diagram, TRACEIT models signal interconnections among system components in data form. |
 | Control-Structure Completeness Checking:It checks the completeness and consistency of the control structure, using standard inspection rules (e.g. verifying that generated signals are referenced in process models). |
 | Automated Fault Impact Assessment:Simulates fault impact analysis by assuming unavailability of individual or multiple system components (entities or connections), or by manipulating shared property values (e.g. platform, location). |
 | Comprehensive Trace Information Throughtout the STPA Process:Throughout the STPA process, TRACEIT provides various trace views (highlighting, abstract views, etc.) to support model review, confirmation, and UCA cause analysis. |
 | Flexible Model Editing and Expansion:Supports incremental modification, supplementation, and extension of existing computalized control-structure data without needing to rewrite the structure from scratch. |
 | Management of Causes & Countermeasures:For each loss scenario (Cause – UCA – Hazard – Loss), TRACEIT helps users develop, organize, and manage associated causes and countermeasures. |
 | Trace View of Analysis Results:Enables trace-based display of the entire analysis and specific items according to user settings, facilitating review, communication, and system improvement. |
