  2. Presentation Sequence • Inputs • KAON summary table (includes all of the inputs) • Management Plan • Requirements (SCRD, SRD, FRD) • Performance Budgets • Trade Studies • System Architecture (see next presentation) • Outputs • Conceptual Designs • Functional Requirements

  3. Inputs: KAONs http://www.oir.caltech.edu/twiki_oir/pub/Keck/NGAO/NewKAONs/KAON_summary.xls

  4. Management Plan • System Design Phase Planning http://www.oir.caltech.edu/twiki_oir/bin/view.cgi/Keck/NGAO/SystemDesignPhasePlanning • WBS dictionary defines each WBS element See appendix 9 of KAON 414 Systems Engineering Management Plan (SEMP) http://www.oir.caltech.edu/twiki_oir/bin/viewfile.cgi/Keck/NGAO/SystemDesignPhasePlanning?rev=2;filename=NGAO_SD_System_Eng_Mgmt_Plan_v20.doc • MS Project Plan defines WBS elements, resources & schedule (see KAON 481 for mid-year replan) http://www.oir.caltech.edu/twiki_oir/pub/Keck/NGAO/SystemDesignPhasePlanning/NGAO_SD_schedule_v26.mpp See next 2 slides • See previous presentation for design phase management details

  9. Outputs The AO system & laser facility design efforts are expected to produce the following: • A revised & complete set of functional requirements for each WBS element • These will be incorporated into the FRD (they should be provided in the FRD format) • FRD configuration management is TBD • Likely 1 person to approve/release minor changes & draw major changes to EC’s attention • These can include redistribution of the performance budgets • One or more design concepts for each WBS element that demonstrate feasibility to satisfy the functional requirements • A KAON documenting the products of each WBS element • Especially, the design concept & its evaluation versus the functional requirements • Also, results of any trades or analyses, identification of any issues and/or technical risks & suggested risk mitigation • Appropriate WBS elements can be grouped together in a KAON • These KAONs will be used as a basis for the preliminary design • Cost information is not an expected output of this phase, however any relevant cost information should be provided for inclusion in WBS 4.1.2 (costing) • The overall design will be documented in the System Design Manual (SDM) with reference to the KAONs and FRD
