---+++++System Architecture Goals
   * Identify & rank candidate architectures
   * Develop architecture system-level cost estimation
   * Progress on subsystem functional requirements
   * Understanding of how the different architectures imply different program structures (for example, a Keck upgrade could offer an incremental approach to development & science return) 

---+++++Reference Material
System Requirements Summary (*Wizinowich*):
   * [[%ATTACHURL%/Architecture_reqment_v6.xls][Science Requirements Summary]] [[%ATTACHURL%/Requirements_Changes.doc][Summary of Required Requirements Changes]]([[http://www.oir.caltech.edu/twiki_oir/pub/Keck/NGAO/NewKAONs/NGAO_SCRD_Release1.pdf][SCRD]] & [[http://www.oir.caltech.edu/twiki_oir/pub/Keck/NGAO/NewKAONs/KAON456_NGAO_SRD_v1.11.doc][SRD]]). 
Architecture Report Contents:
   * Revised working definition of each candidate architecture (e.g. marked up architecture poster)
   * Summary of requirements satisfaction (e.g. areas of performance concern)
   * Summary of technical pros and cons, including major risk items
