So many questions!
How about uptime?
What about
compliance?
What about old
software?
What to do with
current provider
contracts?
How much this will
cost?
What about my job
position? Will it
change?
How can we hire new
people competing
against big players?
How can we uptrain all
our current
Engineers?
What about our
outsource team?
How to get onboard
the C-level
executives?
How this will affect
Business As Usual
How this will align with
ITIL/ITSM?
