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 moneySpend 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
