SafetyCase::LifecycleStageKind

The SafetyCase should be initiated at the earliest possible stage in the safety program so that hazards are identified and dealt with while the opportunities for their exclusion exist. <br/><br/>The LifecycleStageKind is an enumeration metaclass with enumeration literals indicating safety case life cycle stage.<br/><br/>Semantics:<br/>The safety case is one incremental safety case, rather than several complete new ones. The safety case lifecycle stage has the following meanings:<br/><br/>- The preliminary safety case is started when development of the system is started. After this stage discussions with the customer can commence about possible safety issues (hazards). <br/><br/>- The interim safety case is situated after the first system design and tests.<br/><br/>- The operational safety case is prior to in-service use. <br/><br/>Extension: <br/>Enumeration, no extension.<br/>
