15. DevOps journey – Where to start?
Asses where you are
• Gather
information
about MTTR,
MTTD, rates of
deployment
• Microsoft’s
DevOps Self
assessment*
Challenge people
• Address people
on collaboration
between dev and
ops
• Thinks out of the
box instead of in
organization
structure and
processes like ITIL
Determine your
tools
• Choose the
practices you
need
• Define the tools
that are suited to
your case
MTTR=Mean Time To Resolve
MTTD=Mean Time To Detect
