The DALs  for the alternatives are then included in the IAP and  ISPD prior to the IID.  In the Initial IA phase, the Initial Business Case considers at least three alternative approaches  for achieving the desired capability. In each case, the alternatives are evaluated against the  legacy case or status quo in terms of lifecycle  cost, operational benefits, safety, and risk.  The IID requires an initial ISPD. The ISPD provides the investment decision authority a  summary of the plans for the  SI phase of the proposed investment. It conveys the most critical,  relevant, and meaningful information to support JRC decision making. In the ISPD, the PO must clearly explain the scope of the safety effort and describe a  high-confidence program implementation plan. Within the ATO, the ISPD is approved by both  the Vice President of the organization executing the program and the ATO Chief Operating  Officer. Certain sections of the ISPD are reviewed and approved by specific executives,  including the Vice President of AJI.  The TEMP is the primary test management document for an acquisition program throughout its  lifecycle. It delineates all activities that must be performed to achieve the goals of Verification  and Validation (V&V). It also documents the Test and Evaluation (T&E) methodologies that will  be used to assess safety hazard controls and security risks. The preliminary TEMP describes  the investment program test strategy and scope. It is developed based upon the concepts and  functions documented in the pPRD prior to the IID and is not expected to contain the complete  level of detail required to fully implement the T&E program.  The PMP defines how the service organization manages the investment program to execute the  strategy recorded in the ISPD. It defines the relationships and responsibilities of key  organizations that contribute to the implementation and fielding of this initiative. All investment  programs that have a safety impact on the NAS are required to execute a system safety  management program as specified in the PMP.  The FID is the point at which the JRC approves the investment program, sometimes with  Record of Decision changes and special direction. System safety has a twofold purpose  leading up to the FID:  This early assessment allows for informed, data-driven decisions.  To support the FID, a PHA is completed to inform the PO and JRC of the risk ratings for the  program. The required work products of the Final IA phase must be verified and validated  (according to the AMS V&V guidance) prior to the FID. If the JRC accepts the  recommendations, it approves the investment program for implementation; delegates  • To develop early safety requirements that form the foundation of the safety and systems engineering efforts, and • To provide objective safety data to aid acquisition management in making decisions. 2_SRMGSA_202003  Originally published March 2020  Uncontrolled copy when downloaded  1
