Schedule estimates and cost appraisals were developed for each activity. While past surveys have focused solely on the cost, the current survey committee believes that this number, although important, is only part of the story.

new worlds, new HorIzons astronoMy astroPHysIcs In and The parallel implementation of the committee and CATE processes, shown in Figure 7.1, allowed for timely and efficient data gathering and fact finding by the CATE contractor and the committee while maintaining the independence of each activity. As one of the first activities of the survey, before the CATE process was fully developed, the committee solicited Notices of Intent (NOI)

Furthermore, the size and cost for large ground projects have approached those being built for space only in the past decade. Each of the ground-based projects evaluated in the CATE process required an extrapolation from existing facilities using key discriminating factors following the process shown in Figure C.2.

The contractor had no independent basis for evaluating the operations costs estimates provided for any ground-based project. Those appraisals were constructed by the survey committee on the basis of project input and the ex perience and expertise of its members.

Contractor appraisals of cost are by work breakdown structure element. ePO, education and public outreach; MOS/GDS, mission operation system/ground data system; PM/Se/Ma, program management/system engineering/mission assurance.

Note that the costs shown do not match those shown in Figures C.4 and C.5, because the costs for Phase a, technology development, Phase e, launch vehicle, and launch vehicle threats were removed to allow for direct comparison of the three missions with recent and historical missions of similar scope. Costs are in FY2010 dollars.
