Major Issues to Be Addressed

• Research and education organisations are
  evaluated only with direct quantitative measures
  (amount of publications, external funding and
  graduated students) instead of qualitative ones
  (strategic value of publications, projects and
  educational profiles)
• Wrong values are gaining importance (money is a
  key issue for most decisions, in universities key
  persons are exhausted with secondary level work)
• The main objective seems to be maintaining a
  stable state instead of aggressive search for
  continues changes (funding mechanisms, research
  directions, course contents)
• There is no common strategy and roadmap processes
  to support funding, research and educational
  organisations, and enterprises (too many
  decisions are based on very narrow and short-term
  thinking)
