DevOps and Friends — ITSM
ITIL®
“ITIL and ITSM still are best codifications
of the business processes that underpin
IT operations, and actually describe
many of the capabilities needed into
order for IT operations to support a
DevOps-style work stream.”

Questions to Ask Yourself
Current Culture – Do you collaborate, share, learn and trust or are you engaged in
religious wars between Dev and Ops?
Management Support – Will your leaders walk the talk? Failure to do so just gives
succour to those that don’t want to change.
Do people understand the need? Often DevOps practices are a response to
serious business issues (Read “The Phoenix Project”). Most of the time, if people
understand that, they are more willing to lend a supporting hand.
Can we ease the pain? Change is hard. Can we make it more acceptable by
utilizing existing processes and tools?
