Content:
fety analysis be performed and documented on each of the principal design documents: requirements, design descriptions, and source code. Hazards, including abnormal events and conditions and malicious modifications, should be analyzed and documented. Hazard reduction efforts should be documented. BTP 7.14-36 Revision 6 - August 2016 B.3.1.9.2 Implementation Characteristics of the SSP The implementation characteristics that the SSP should exhibit include measurement and procedures. Measurement concerns a set of indicators used to determine the success or failure of the software safety effort. The SSP should require that software safety data be systematically collected and analyzed to determine the effectiveness of the software safety effort. Procedures involve a description of the software safety strategy. The SSP should describe the management of the software safety activities within the development organization. It should provide procedures for resolving safety issues. The SSP should require that problems encountered in implementing the safety program be brought to the attention of the project manager. A procedure should exist for assuring resolution of identified unacceptable risks. The SSP should describe methods to be used to implement each safety task. A method should exist to identify hazards caused by software, and to identify hazards whose resolution will be under the control of software. The SSP should require that appropriate safety requirements be included in the software requirements specification. It should define the safety-related activities to be carried out for each set of life cycle activities, from requirements through operation and maintenance. The SSP should identify all documentation required for the proper and safe operation of the software. Procedures should require monitoring the software safety function performance during operation of the system. The SSP should require that hazards identified by plant safety analysis, system safety analysis
