Using STPA on Organizational Components of the Safety Control Structure

6 Using STPA on Organizational Components of the Safety Control Structure 

The examples above focus on the lower levels of safety control structures, but STPA can also be used on the organizational and management components. Less experimentation has been done on applying it at these levels, and, once again, more needs to be done. 

T vo examples are used in this section one was a demonstration for NASA of risk analysis using STPA on a new management structure proposed after the Columbia accident. The second is pharmaceutical safety. The fundamental activities of identifying system hazards, safety requirements and constraints, and of documenting the safety control structure were described for these two examples in chapter 7. This section starts from that point and illustrates the actual risk analysis process.
