Why Would a PDR be Why Would a PDR be DisapprovedDisapproved

• Your mission objectives are inappropriate• “We plan to fly a rock!”

• You did not “think the problem through”• “We will measure the temperature of the jet

stream using the rocket platform.”

• You exceeded a major constraint.• “Our multi-wavelength spectrometer weighs

30 kgs, costs $30,000, and won’t be ready until Fall 2005!”
