3. IMPACT™ Science & Engineering Associates, Inc. Integrated Messaging and Process Analysis Control Techniques IMPACT Software Safety Process The integration of the “Software Assurance” of RTCA/DO 178B and “Software Safety” of Mil-Std 882 ensures a total integration of system safety engineering, system engineering and software development methodologies for a safer system. The process as defined below produces the necessary output products to support system certification and safety requirements criteria. System Hazards Analysis The Functional Hazard Analysis is a natural springboard into the safety activities required by Mil-Std 882. The most important step in the process is the in-depth analysis to identify failure modes or pathways to the identified hazards of the system. This analysis includes the identification of each hardware, software, and human interaction on the failure pathways. System Functional Analysis Analysis is accomplished to determine system functionality and the ramifications of “loss of functionality”. This activity is accomplished in conjunction with systems engineering and can be used to supplement interface and integration activities. The primary purpose is to identify the Safety-Critical Functions (SCF) of the system and categorize them in accordance with DO-178B safety level criteria. The SCF’s is then tied to the software functionality to determine which CSCI’s or CSU’s will be determined to have significant safety impact. This allows functionality to be allocated to the appropriate safety levels within the software design architecture. Identification of Software Safety Requirements The in-depth hazard causal analysis defines the interaction of hardware, software, and the human as contributors to potential mishaps. The results of this analysis is a more refined list of hazard mitigation requirements for hardware and software design, safety and redundant systems, fault detection, tolerance, and recovery, and procedures and training. The safety engineering team then ensures that the domain experts (designers) successfully implement the defined hazard mitigation requirements. This is accomplished through a variety of analysis, inspection, and test activities. SEA Inc.
