Analyze control measures
This step analyzes the proposed solutions to ensure that they provide adequate risk mitigation and meet the other, possibly
opposing, design constraints in an optimal way. This analysis is often done in the form of an FTA or FMEA. |
Integrate safety and reliability patterns into architecture
This step elaborates the architecture to include the safety and reliability design patterns, that is, implement the control
measures at the architectural level. |
Select design solutions to add control measures to mitigate risks
Based on the nature of the risks and the other design constraints, different design patterns may be more optimal than
others. This step selects one or more such patterns. See DOU02 for more information on safety-related design patterns. |
Review the hazard analysis
The hazard analysis is usually initially created during requirements definition (see Task: Manage Safety and Reliability
Requirements). This document initially identifies hazards, risks, basic faults, and (possibly) control measure meant to
mitigate the risks. |
