1.0 PURPOSE/SCOPE

1.1 Purpose

This TRD shall become the Supplier’s SOW for the B-52 WBSI contract and defines contractual obligations for which the Supplier shall be responsible if awarded.

1.2 Scope

This document lists the Supplier’s major program milestone schedule, hardware, data, and support requirements for the B-52 WBSI Program.

2.0 PROGRAM MANAGEMENT

2.1 Integrated Master Schedule (IMS) and Supplier Status Reports (SSRs) The Supplier shall deliver a comprehensive IMS as an appendix to the proposal. It shall contain all critical events, milestones, completion criteria, predecessors, successors and their dependencies while providing clear evidence of the Supplier’s understanding of all program objectives, major milestone, and schedule requirements. The IMS shall facilitate critical path analysis. Following award, the Supplier shall maintain and provide monthly updates/revisions to the IMS (changes clearly identified) throughout the duration of the program, including the retrofit phase. The Supplier shall not revise contractual deliverable/milestone dates without Government approval. (Reference DID DI-MGMT-81650, CDRL A001.) The following event schedule is provided to clarify the Government’s required critical milestones necessary for meeting the overall program schedule.

The Supplier shall deliver a detailed SSR no more than one month After Receipt of Order (ARO) and every month thereafter throughout the duration of the program. The SSR shall summarize current activities, document progress toward upcoming milestones, provide an updated IMS, identify problems/concerns, and outline mitigations/solutions as necessary. (Reference DID DI-MGMT-80227, CDRL A017.)

2.2 Supplier Performance Review Board (SPRB) Meetings

The Supplier shall attend and facilitate SPRB meetings. The initial meeting shall serve as a Program Kick-Off meeting and shall be conducted no later than one month ARO.

Subsequent meetings shall be called on an as-needed basis and hosted by the Government and shall be conducted at locations designated by the Government (which may or may not include the Supplier’s facility). The Supplier shall provide agenda/data inputs to support these meetings. The meetings shall support review of the IMS and the Supplier’s strategy to comply with all contractual requirements. (Reference DID DI- ADMN-81249B, CDRL A003 and DID DI-SESS-81766, CDRL A002.)

2.3 Technical Interchange Meetings (TIMs)

The Supplier shall support TIMs via teleconferencing or at locations as determined by the Government. These meetings will be conducted monthly (schedule to be determined after contract award) and chaired by the Government for the purpose of reviewing overall program and technical progress. Meeting frequency may be increased to bi-weekly as determined necessary by the Government during critical periods of the program such as qualification testing, if schedule milestones are at increased risk for delay, or if problems arise. The Supplier shall provide agenda inputs/data to support these meetings. Required actions, many of which will be the responsibility of the Supplier, will be identified and documented by the Government in meeting minutes and action lists. (Reference DID DI-ADMN-81249B, CDRL A003.)

2.4 Preliminary Design Review (PDR)

The Supplier shall host a PDR at the Supplier’s facility or at a location designated by the Government. The PDR meeting shall be completed no later than 3 months (ARO). The Supplier shall deliver pre-PDR data and briefing materials no later than 15 calendar days prior to the meeting to enable Government review/preparation. The PDR shall provide the Government with an opportunity to consider design concepts/options and establish which configuration(s) should be subjected to development testing/analyses.

Additionally, the PDR will enable the Supplier and the Government to coordinate on program issues and contract requirements. The Supplier shall provide agenda inputs to support a combined Government/Supplier agenda. (Reference DID DI-ADMN-81249B CDRL A003 and DID DI-SESS-81766, CDRL A006.)

The Supplier shall host a CDR at the Supplier’s facility or at a location designated by the Government. The CDR shall be completed no later than 15 months ARO. The Supplier shall deliver pre-CDR data and briefing materials no later than 15 calendar days prior to the meeting to enable Government review/preparation. The CDR shall provide the Government with an opportunity to evaluate/approve the Supplier’s final design based on testing and analyses. Additionally, the CDR will enable the Supplier and the Government to coordinate on program issues and contract requirements. The Supplier shall document anticipated hardware performance and the intended method of verifying compliance for each individual technical requirement contained in the B-52 WBSI Performance Specification (PS) 201913664. The Supplier shall provide agenda inputs to support a combined Government/Supplier agenda. (Reference DID DI-ADMN- 81249B CDRL A003 and DID DI-SESS-81766, CDRL A007.)
