7. Outline of Collaboration with Universities • NTT collaborates (joint research and commissioned research) with universities in expectation of a win-win situation. • NTT contributes to university education through lecturers and internships. • Joint research projects: about 300/year (about $4.5 Million) • Commissioned research projects: about 100/year • Lecturers at universities: about 150/year • Students at summer internship: about 50-100/year

8. Umbrella Collaboration Scheme with Universities (1) • The previous collaboration scheme with universities has some issues in advancing “open innovation” in R&D. Issues Drawbacks A narrow outlook on research scope Person to person collaboration Time consuming to conclude contract Negotiation of collaboration contract Little business creation Academic paper is major research result Professor Researcher Collaboration Issues in previous collaboration scheme

9. Setting of designated goals and evaluation of research results Progression in quality Umbrella Collaboration Scheme with Universities (2) • NTT has promoted the “umbrella scheme” as a collaboration scheme with dominant domestic universities since 2004 for better quality of research results. Purpose Sub-scheme Discussion of direction by Executive Board Introduction of “PDCA” cycle Quick and timely collaboration Umbrella agreement on intellectual property Business creation NTT University A Laboratories Service Integration Laboratories Executive Board A Department Department of Industry-Academia Collaboration • Strategic planning of • projects • Matching teams between univ. and NTT • Progress management of projects B Laboratories B Department B研究所 B研究所 ･･ ･･ Intellectual Property Center Intellectual Property Center New collaboration scheme

10. Umbrella Collaboration Scheme with Universities (3) • NTT has concluded contracts with seven universities • Kyushu University, Osaka University, Keio University, Nagoya University, Kyoto University, The University of Tokyo, Waseda University • Conditions for “umbrella agreement” with a university • Organization of Executive Board • Intellectual propertyagreement • Collaboration with NTT operating company • Existence of mutually interesting field for win-win collaboration Kyoto University Advanced communication environment Collaboration agreement ceremony with Waseda University Waseda University Optoelectronic devices and network platforms in ICT Kyushu University Combining humanities and sciences in ICT Keio University Ubiquitous networking in ICT The University of Tokyo Security in information & telecommunications Nagoya University Applications in ICT Osaka University Networking in ICT

12. Collaboration for Making Software (1) ■ Outline • NTT asksuniversities to make experimental software for research • Collaboration produces software, data, patents, evaluation reports of NTT’s techniques, etc. ■ Purpose • Mutual activation of research and/or education based on following merits 【 Merits 】 ＜University＞ - Training of students under real projects - Getting ideas for new research - Human exchange - Getting budget for research ＜NTT＞ - Getting ideas for new research - Reducing cost of making software - Human exchange

14. Collaboration for Making Software (3) ■ Results and evaluation • After discussion with universities, software specifications were brushed up. • The software quality is equal to that made by a software house. • New projects were created through this collaboration, e.g., joint projects, individual projects in universities and NTT. • Some software made in these collaborations was used in business products. • Collaboration was effective for increasing students’ skills. • Cost for making software was decreased by about 50%. Win – Win collaboration

15. 共同研究 共同研究 Collaborative research Future Direction of Collaboration • Number of collaborating universities will increase. • Strategic collaboration themes will be sought for open innovation. • Core collaboration themes and/or research will be produced. • New businesses will start up based on collaboration results.
