7 stages of change management from Visible Ops

From The Visible Ops Handbook,

1. Oblivious - "Hey, did the switch just reboot?"
2. Aware - "Hey, who just rebooted the switch?"
3. Announce - "Hey, I'm rebooting the switch. Let me know if that will cause a problem."
4. Authorise - "Hey, I need to reboot the switch. Who needs to authorise this?"
5. Schedule - "When is the next maintenance window - I'd like to reboot the switch then?"
6. Verify - "Looking at the fault manager logs, I can see that the switch rebooted as scheduled."
7. Manage - "Let's schedule the switch reboot to week 45 so we can do the maintenance upgrade and reboot at the same time."
