NASA Internal Memo: Orion DAC2 Architecture Closure Plan Rev E, 2/19/08

“This memorandum describes the process for closing the Orion architecture in DAC-2. It lists the open architecture issues, threats and opportunities and requirements issues that need to be addressed as well as the overall schedule for this activity. The original plan for DAC-2 had the architecture-level decisions closed by the Architecture ERB that was held February 22d-28th and rolled up to the integrated system by the Mid-Term ERB on February 29th Since a number of significant system-level trades and studies are still open, the project requires an intensive effort over the coming weeks to close these issues in order to proceed with the preliminary design tasks required for PDR.”
