33. Summary Present status: Upgrade 1 Phase / Find individual solutions Next steps: complete control by VISTA / till end 2003 Our experience: Main question: Own solution versus Commercial solution Need manpower Need money Spend time Could save time...need more $ ?... save more $ ? We use VISTA because:No manpower,Not so much time, Want a ‘State of the Art’ solution,Long time support of OS
