Conclusions
Design to cost considered throughout life
CoDR separate with cost targets as requirement
- not formally committed to full costs
- serious effort to investigate feasibility and risks
- if very high risks, propose intermediate steps or development
- refine science and engineering requirements with detailed flowdown
- consider major trades at this time, including engineering trades
- identify contingency appropriate to completing the project beyond CDR
Balance engineering considerations from the beginning
- day 1 of beginning conceptual work
