Appendix D. Human-Rating Certification Package

D.1 The form of the HRCP is a compilation of pertinent plans and documents, plus presentation material to help guide reviewers through the package. The HRCP is not intended to duplicate/repackage existing program documentation but rather provides a summarization of information the details of which can be found in referenced documents or other data sources and justification/explanation/augmentation for information that isn't available in other documentation). The HRCP must be maintained under configuration management (especially to referenced/linked material) to clearly track changes made between milestones.

D.2 Refer to the referenced paragraphs for the detailed requirement text and delivery milestones. The material provided prior to and during each milestone review will be considered draft and for review and comment. An update will be provided after all changes resulting from the review have been incorporated. The post-review HRCP will be maintained in a location and in a manner that supports review by designated Technical Authorities and JSC Center Director representatives and designated review panel members.

D.3 The final HRCP submitted for approval and granting of a Human-Rating Certification will be provided in a manner as prescribed by the Program Management Council.
