tooling

It's not the team in
charge of delivery

It's not yet another silo
between devs and ops

12. @krisbuytaert
#devopsengineers

It's not a job title.

Is it a system engineer writing code ?
●
Is it a developer running operations ?

Is your organisation agile,
or just your silo ?

And they probably don't need a
budget, or a different one

#enterprise devops
●
“You can only change
small organisations”
●
“You can't change a
large organisation”
●
“You need to do things
different“
●
There is much more to
change
●
It takes longer
●
The resistance is bigger
●
“The antibodies kick in”
