Outputs | Finite set of already known and used Control Measure to cope with hazards (as mindmaps): https://rmt.jaas.service.deutschebahn.com/confluence/display/SSI/Safety+functions See subpages sorted by accident. |
Methodology | Control measure (CM) are used on operational level. The control measure shall avoid a hazard or mitigate a hazard. Following steps have been aplplied in order to create a set of suitable control measures: 1) Identify already existing control measures resp. system (safety) functions The different railway standards have been analyzed (see Input) in order to identify safety functions which can mitigate identified hazards or their failure modes. 2) Define control measures to mitigate hazards/to negate their conditions For every hazard/its condition or failure mode a minimum one control measure has been assigned in the mindmaps created during hazard-accident assignment process. 3) Consolidate the set of identified control measures and system (safety) functions The list of identified control measures/safety functions have been mapped to the control measures assigned to the identified hazards and hazard failure modes. Where necessary new control measures have been defined in order to suit to the failure mode/hazard, where possible the established safety functions or their adaptations have been used. |

Completion criteria | List of consolidated control measures applied to all before identified hazards and their failure modes sorted by accident; no further Control Measures needed for Risk Managemet Procedure |
Design review | Link to the corresponding design review where the completion of this activity is evaluated. Remark: Internal review is documented in list in Safety functions (MMs with CMs) (still no quality management process in DBS). |

Provides input to/assists (Contributes) | other RAMS Expert, Risk Manager or System Architect |
Uses outputs (Informed) | Identify the roles and/or process areas that make use of this information outside of the ARCH process area; The consolidation of the list of control measures is a basis for the implementation of state model in Capella. |
