2. Timeline Project Timeline Week 5 - PDR complete by end of week
DURING: Evaluation of design alternatives for each phase
END: PDR is update to MDR, final design requirements are documented
END: Will have X1 and X2 complete by end of week to satisfy PDR requirements
Week 6-7 – CDR complete by end of week (~3 weeks away)
DURING: Evaluation of design alternatives for each phase (priority). If subsystem has already reached maturity and we are fairly confident of its selection, perform detailed analysis (sub-priority)
END: All design alternatives will have reached maturity
END: “Alternative Design Freeze” - no other alternatives will be able to be analyzed
END: Selection of final configuration
END: Draft writing begins
Week 8-9 – Final Design Freeze at end of week (Spring Break!)
DURING: Detailed analysis on selected mission configuration. Changes to configuration will be made only if serious issues occur.
END: Final mass/power/volume budgets set for all phases
END: Draft writing nearly complete (due Wed. after spring break to PM)
After Spring Break – Crunch time
2 weeks until your final report due to PM
2 weeks + weekend until your final slides due to PM

Week 5
Week 6

Week 8
Week 9 M W F
PDR Complete
Design Freeze (Mass/Power/Volume set)
Draft Writing
Evaluation of design alternatives (all phases)
All design alternatives reach maturity and freeze
Selection of final configurations
Detailed analysis of X1, X2
Detailed analysis of final configurations

4. Today Separate alternative designs into three levels:
Preliminary scalability analysis (almost) complete (X2)
Have power to focus on alternative designs (X3,X4)
Numbers from X1,X2 analysis will indicate if design changes will benefit system
Separate alternative designs into three levels:
Level 1: Large system change, possibly affecting more than one phase
Level 2: Medium system change, has a > 10% affect on mass, power, volume from X1 or X2 for a particular phase
Level 3: Small system change, < 10% affect on mass, power or volume from X1 or X2 but can make integration simpler, system more reliable, cheaper, etc.
Most promising alternatives for each phase will be listed today
Each level 1 and 2 alternative assigned a POC (Point of Contact) and APOC (Alternative POC) by Phase lead
Each level 3 alternative assigned a POC by Phase lead
Will provide responsibility and set deliverables for POC (can be used for presentation material)

5. Alternative Design Deliverables (not complete)
Order-of-magnitude mass/power/volume savings (kg,W,m^3)
Potential complexity/cost/ease of integration savings
Complexity of analysis (days to reach maturity)
Recommend use for GLXP size?
Recommend use for arbitrary payload size?

6. To-Do POC PM Upload Design Alternative List (by 4:00PM)
Upload Design Alternative form (by tomorrow)
Upload Draft writing expectations (by tomorrow)
Phase Leader
Assign POC to all design alternatives, modifying Design Alternative List (by 8:00 PM)
POC
Complete Design Alternative form (by 6:00PM Monday 2/16)
