| 2.3.9-1-1 Ensure adequacy of survivability requirements in the request for proposal and contract |
Phase 0 |
Phase A |
Phase B |
|
Ensure requirements specify that the prime contractor has a survivability and vulnerability program, and that it delivers a plan that sufficiently defines threats, and adequately mitigates those threats as a systems engineering discipline. Ensure prime's top management is required to review the survivability plans at periodic intervals for adequacy and effectiveness.

| 2.3.9-1-2 Ensure requirements address the complete environments description |
Phase 0 |
Phase A |
Phase B |
|
Ensure review of requirements. Natural radiation environments descriptions for space have in the past had built-in conservatism to allow for uncertainty. Satellite-based data accumulated over many years has allowed more accurate determinations of these environments. This in turn allowed cost saving in designs by allowing less conservative design margins. Man-made radiation environments from nuclear weapons have also undergone evolution as knowledge of adversary capabilities advances. Organizations such as the AF Nuclear Weapons Center and predecessors have generated nuclear weapons environments in forms appropriate for designers. Since nuclear, laser and radio-frequency hardening are so specific to the particular hardware and mission, most programs need custom environments. Thus during the concept phase it is important that the planners generate, or have generated, program-specific weapons environments. The government has classified studies on laser environments.

| 2.3.9-1-3 Ensure deliverable documentation allows ongoing oversight |
Phase 0 |
Phase A |
Phase B |
|
Ensure Deliverable Survivability Data includes the following: Survivability and Vulnerability Program Plan; Survivability Trade Study Report; Hardness Assurance Plan; Hardness Maintenance/Hardness Surveillance Plan; System Survivability Test/Analysis Report. List representative DIDs specifically formatted for nuclear survivability documentation. Include specialty engineering. This subtask goes along with the signature authority task. The Survivability organization needs access to and signoff provision for survivability-related program documentation to assure continuity of the survivability implementation process.

| 2.3.9-1-4 Ensure government survivability signature approval authority |
Phase 0 |
Phase A |
Phase B |
Phase C |
Phase D1 |
|
Ensure government Survivability organization has signature approval authority on survivability-related studies, reports and verification activities to maintain hardness assurance throughout the life of the program. Signature approval authority is also necessary to ensure that the Survivability organization is kept "in the loop."

| 2.3.9-1-5 Ensure government-furnished items are addressed |
Phase 0 |
Phase A |
Phase B |
Phase C |
|
Ensure the contracting authority specifies interfaces and support connections are completely described in the contractual documents. These provisions must be in the Work Breakdown structure, and the contractor must have cost estimates for all phases of the program. The contracting authority, not the contractor, is responsible for specifying the actions that ensure the performance of government-furnished items. Ensure that the contractor include government-furnished equipment in its reliability and other allocations.
