12. 20 April 06 P5 - SLAC Global Design Effort 12 Elements of the ILC R&D Program R&D in support of the BCD –Technical developments, demonstration experiments, industrialization, etc. Proposal-driven R&D in support of alternatives to the baseline –Proposals for potential improvements to the baseline, resources required, time scale, etc. –Guidance from Change Control Board Develop a prioritized DETECTOR R&D program aimed at technical developments needed to reach combined design performance goals

13. 20 April 06 P5 - SLAC Global Design Effort 13 Global R&D Board (RDB) The Global R&D Board will be responsible for assessing and providing guidance for the overall R&D program. The RDB will suggest priorities for the research facilities and R&D supporting the baseline, the R&D on alternatives to the baseline and selective R&D that could further the field in the longer term. The mission will also include global assessments and recommended priorities for the detector R&D program and evaluate the balance between accelerator and detector R&D. The RDB will develop a proposal driven program, structured in the sense of defined goals, and milestones, and resources evaluated on a common basis to allow comparison across different regions and national funding systems. It will conduct reviews and identify gaps in coverage of topics, resource or technical issues, duplications, and other concerns..
