  • Space (storage before and during execution)
  • User experience
  • Security, portability, etc

• How can you resolve conflicts?

• What mix of automatic/portable vs manual/slow/error-prone?

EXAMPLE: TW; speed, UI response and network latency and cost all wrong, but space an absolute constraint. Ordered space, UI, network.

• Try to find tools to objectively measure according to your metrics

• Iterate

• Everything is more muddy with multiple targets
