10. XSEDE : Governance Leadership – partnership led by NCSA, NICS, PSC, TACC and SDSC: CI centers with deep experience – partners who strongly complement these CI centers with expertise in science, engineering, technology and education Balanced governance model – strong central management, rapid response to issues and opportunities – delegation and decentralization of decision-making authority – openness to genuine stakeholder participation stakeholder engagement, advisory committees – improved professional project management practices formal risk management and change control 10

11. XSEDE: Extending Impact Coordinated national program with greater scope and scale – increased diversity of topics, modes of delivery, and reach to new communities and audiences – broaden participation among under-represented communities Campus bridging for effective use of CI resources – more tightly integrate with campuses through expanded Champions program and additional bridging activities Establish certificate and degree programs – institutional incorporation of CS&E curricula; professional development certificate – prepare undergraduates, graduates and future K-12 teachers 11

13. XD Coordination and Management Service - design of the grid architecture - management of its implementation - management of accounting, authorization, authentication, allocation and security services, - coordination of the component services - maintenance of a responsive, user-centric operational posture - coordination of those service providers that provide access to physical resources 13

14. Technology Audit and Insertion Service - quality assurance and quality control - review and test advanced software tools for manipulating, processing and analysing very large amounts of information - testing advanced software tools and developing deployment strategies, in partnership with the relevant service providers. 14

15. Advanced user support” support of researchers or research groups running complicated computer programs, researchers or research groups attempting to develop and use complex workflows, and researchers or research groups trying to develop or implement science gateways 15

16. Training, Education and Outreach Service training for staff, current users and prospective users integration of research and education broadening of participation in science and engineering that exploits by under-represented groups. 16

17. XSEDE : User Services Unified and comprehensive user support services – designed to advance science and engineering – provided by experts in the application of technology – new and expanded facets of advanced support More mature operational practices – increased focus on productivity and ease of use – increased and enhanced security, reliability, and quality assurance 17
