Figure 5.3 Product Line Technical Review Schedule
5.1.6
Three points are important: (1) Management reviews and the technical reviews support one another. (2) Technical reviews are completed before a KDP. (3) Technical reviews are event based and occur when the entrance criteria for the applicable review as specified in Appendix G are satisfied. They occur based on the
maturity of the relevant technical baseline as opposed to calendar milestones (e.g., the quarterly progress review, the yearly summary).
5.2
Technical Review Requirements
5.2.1.1
For each product line (BAR, ATD, IP, and FS&GS), technical efforts are monitored throughout the life cycle to ensure that the technical goals of the project are being achieved and that the technical direction of the project is appropriate.
5.2.1.2
Technical teams shall monitor technical effort through periodic technical reviews.
5.2.1.3
A technical review is an evaluation of the project, or element thereof, by a knowledgeable group for the purposes of:
a.
Assessing the status of and progress toward accomplishing the planned activities.
b.
Validating the technical tradeoffs explored and design solutions proposed.
c.
Identifying technical weaknesses or marginal design and potential problems (risks) and recommending improvements and corrective actions.
d.
Making judgments on the activities' readiness for the follow-on events, including additional future evaluation milestones to improve the likelihood of a successful outcome.
e.
Making assessments and recommendations to the project team, Center, and Agency management.
f.
Providing a historical record that can be referenced of decisions that were made during these formal reviews.
g.
Assessing the technical risk status and current risk profile.
5.2.1.4
See NPR 7120.5 for major program and project reviews and independent reviews.
5.2.1.5
Technical reviews are used to evaluate the status of the technical progress and are supported by other equivalent technical discipline
activities, including safety reviews.
5.2.1.6
The technical team shall ensure that system aspects represented or implemented in software are included in all technical reviews to demonstrate that project technical goals and progress are being achieved and that all NPR 7150.2 software review requirements are implemented.
5.2.2
Planning and Conduct
The technical team shall develop and document plans for technical reviews for use in the project planning process. The technical review schedule, as documented in the SEMP, will be reflected in the overall project plan described in NPR 7120.5. The results of each technical review will be used to update the technical review plan
as part of the SEMP update process. The review plans,
data, and results should be maintained and dispositioned as Federal records.
5.3.1
Definition of Minimum Required Reviews
5.3.1.1
The minimum set of required technical reviews applies to all current and future NASA FS&GS and IP programs and projects as defined in section P.2 of this document (including spacecraft, launch vehicles, instruments developed for space flight programs and
projects, designated research and technology developments to be incorporated by space flight programs and projects, critical technical facilities specifically developed or significantly modified for space flight systems, information systems and technology that support space flight programs and projects, and ground
systems that are in direct support of space flight operations). Between each life-cycle phase, a program or project goes through KDPs preceded by one or more
reviews that enable a disciplined approach to assessing programs' and projects' readiness to progress to the next phase. Allowances are made within a phase
for the differences between human and robotic FS&GS projects. Additional description
of technical reviews is provided in the NASA Systems Engineering Handbook (SP-6105). (For more information on program and project life cycles and management
reviews, see the appropriate NPR, e.g., NPR 7120.5.)
5.3.1.2
The technical team shall address the entrance and success criteria listed in Appendix G for applicability to the respective reviews.
5.3.1.3
The technical team shall execute the required Program/System Requirements Review (P/SRR) and Program Approval Review (PAR) in accordance with the review entry and success criteria defined in tables G-1 and G-2 of Appendix G.
5.3.1.4
The technical team shall execute the required program technical reviews in accordance with the following timeline: P/SRR before KDP 0 and PAR before KDP 1.
5.3.1.5
For human FS&GS projects, the technical team shall execute the following required minimum set of technical reviews in accordance with the review entry and success criteria defined in tables G-3, G-4, G-6, G-7, G-8, and G-10 through G-18 of Appendix G: Mission Concept
Review (MCR), System Requirements Review (SRR), System Definition Review (SDR), Preliminary Design Review (PDR), Critical Design Review (CDR), System Integration Review (SIR), Test Readiness Review (TRR), System Acceptance Review (SAR), Operational Readiness Review (ORR), Flight Readiness Review (FRR), Post-Launch Assessment Review (PLAR), Critical Event Readiness Review (CERR), Post-Flight Assessment Review (PFAR), and Decommissioning Review (DR). (For more information on program and project life cycles and management reviews, see the appropriate NPR, e.g., NPR 7120.5.)
5.3.1.6
For robotic FS&GS projects, the technical team shall execute and document the following minimum required technical reviews: the MCR, SRR, Mission Definition Review (MDR), PDR, CDR, SIR, TRR, ORR, FRR, PLAR, CERR, and DR in accordance with the review entry and success criteria given in tables G-3, G-4, G-5, G-7, G-8, G-10, G-11, G-13 through G-16, and G-18 of Appendix G.
Robotic projects can combine the SRR and MDR based on size and level of risk.
If the two reviews are conducted separately, Table G-4 will be used for the SRR
and Table G-5 will be used for the MDR. If the two reviews are combined, the
entrance and success criteria for both SRR and MDR will be combined for this single review.
5.3.1.7
The technical team shall also execute a Production Readiness Review (PRR) as an additional technical review for both human and robotic FS&GS projects developing or acquiring multiple or similar systems greater than three (or as determined by the project) in accordance with the review entry and success criteria defined in Table G-9 of Appendix G. Any project producing end products with three or less units will still perform the required CDR. The CDR will include production considerations when a PRR is not performed.
5.3.1.8
The technical team shall execute the required FS&GS project technical reviews in accordance with the following timelines:
a.
MCR prior to KDP A.
b.
Human FS&GS project SRR prior to SDR and robotic missions SRR and MDR prior to KDP B.
c.
Human FS&GS project SDR prior to KDP B.
d.
PDR prior to KDP C.
e.
CDR prior to starting fabrication of system end products and SIR.
f.
PRR prior to starting fabrication of system end products for projects requiring multiple units.
g.
SIR prior to KDP D.
h.
TRR prior to starting product verification and product validation testing.
i.

k.
FRR prior to KDP E.
l.
PLAR after system end product launch.
m.
CERR after PLAR and before KDP F.
n.
Human FS&GS project PFAR at end of flight and before KDP F.
o.
DR after KDP F.
