ware and interfaces between them. Risks involve a description of the methods to be used to reduce safety risks caused by software failures to an acceptable level. The SSP should describe the method to be used to ensure that hazards which software is expected to control are resolved in an acceptable manner. The SSP should include a requirement that a safety 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 7.14-33 Draft Revision 6 - August 2015 BTP 7.14-34 Draft Revision 6 - August 2015 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
