Appendix D. Human-Rating Certification Package

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 as appropriate 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.

The material provided prior to and during each milestone review will be considered draft and for review/comment. An update will be provided after all changes resulting from the review have been incorporated. The postreview 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.

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.
