Appendix G. Life-Cycle and Technical Review Entrance and Success Criteria

This appendix describes the recommended best practices for entrance and success criteria for the life-cycle and technical reviews required in Chapter 5 regardless of whether the review is accomplished in a one-step or two-step process. The entrance criteria do not provide a complete list of all products and their required maturity levels.1 Terms for maturity levels of technical products defined in the tables of this appendix are addressed in detail in Appendix F. Additional programmatic products may also be required by the appropriate governing NPRs for the project/program.


1 Refer to any applicable NPRs, (e.g., NPR 7120.5, 7150.2, 8705.2) and table 5-1 in this document for required products. Refer to NASA-HDBK-2203 section 7.8, if applicable, for guidance on software products.

Tailoring and customizing are expected for projects and programs. The entrance and success criteria and products required for each review will be tailored and customized appropriately for the particular program or project being reviewed. The decision not to tailor and customize life-cycle review criteria should be justified to the ETA.

The recommended criteria in the following tables are focused on demonstrating acceptable program/project technical maturity, adequacy of technical planning and credibility of budget, schedule and risks (as applicable), and readiness to proceed to the next phase. Customized or tailored criteria developed by programs or projects for life-cycle reviews should also be focused on assessing these factors.

Programs and projects use different Appendix G tables for some life-cycle reviews. Programs (except single-project programs) use tables G-1 and G-2 for program-level SRR and SDRs. Projects and single-project programs use the tables starting with G-3.

G.1 System Requirements Review (SRR) for Programs

The SRR for a program is used to ensure that the program’s functional and performance requirements are properly formulated and correlated with the Agency and Mission Directorate strategic objectives.

G.19 Peer Reviews

Peer reviews provide the technical insight essential to ensure product and process quality. Peer reviews are focused, in-depth technical reviews that support the evolving design and development of a product, including critical documentation or data packages. The participants in a peer review are the technical experts and key stakeholders for the scope of the review. Another purpose of the peer review is to add value and reduce risk through expert knowledge infusion, confirmation of approach, identification of defects, and specific suggestions for product improvements.

Table G-19 – Peer Review Entrance and Success Criteria

  1. The product to be reviewed (e.g., document, process, model, design details) has been identified and made available to the review team.
  2. Peer reviewers independent from the project have been selected for their technical background related to the product being reviewed.
  3. A preliminary agenda, success criteria, and instructions to the review team have been agreed to by the technical team and project manager.

  3. Results of the peer review are communicated to the appropriate project personnel.
  4. Spectrum-related aspects have been concurred to by the responsible Center spectrum manager.

*Required per NPD 2570.5.

G.20 Program Implementation Reviews (PIR) and Program Status Reviews (PSR)

PIRs or PSRs are periodically conducted, as required by the Decision Authority and documented in the program plan, during the Implementation phase to evaluate the program’s continuing relevance to the Agency’s Strategic Plan. These reviews assess the program performance with respect to expectations and determine the program’s ability to execute the implementation plan with acceptable risk within cost and schedule constraints.

G.21 Design Certification Review (DCR)

This review is not depicted in the standard life-cycle review figures but has proven useful to larger projects such as human space flight. Projects/Centers may choose to add this review to their standard life-cycle if they feel it is useful. The DCR ensures that the design complies with functional and performance requirements, as demonstrated in verification, validation, and qualification evidence. The certified design forms the basis from which system acceptance will be assessed. A DCR should, ideally, be held after a CDR and before a SAR.

Table G-21 – DCR Entrance and Success Criteria
