• For us: “DevOps is a culture that fosters communication, transparency and collaboration"

• Communication: I’ll stand up and go to your desk if I need to talk to you, you’re more than welcome to do the same!

• Things go over the wall
• No alignment between tech and business
• One-way communications

InfoSec
• No more FUD
• What is riskier to the business?
• Lack of speed is a risk too!
InfoSec
• ITIL: “You keep using that word, I don’t think it means what you think it means”
• People often blame ITIL as an excuse for badly designed processes
• Surprisingly ITIL compliance was not our biggest problem
Compliance
• Audits are still our biggest challenge
• In our case, we have a sponsor (the CTO)
• Someone (who happens to be me) will be held accountable if something goes wrong
Compliance
The bad apples
• We’ve adopted the “No asshole rule"
• There will be obstructive people that won’t embrace change
• If you can't get rid of them, simply let them fade into oblivion
