If performance must be traded, at what level?
At all levels
- If trade is made at low level, use system level error budgets to asses impact of trade at the highest level
- In many cases, low level changes of specs that seem significant, have little to no noticeable impact on system level performance.
- Include telescope, atmosphere, instrument, detector, processing
- i.e. truly systems approach
Actively and aggressively work with science team and customer in trades that may impact performance
