Not changing production systems at will; obviously you need processes and permissions in place to ensure you&#x27;re not just trampling over prod whenever a dev thinks a change should happen.<p>But I&#x27;ve been in corporate environments where &quot;We need to deploy a new instance&quot; requires four weeks of lead time. Or a new release is tested and ready to go, and rather than just running Chef to deploy it, both the devs and the devops people had to work with a team whose sole job was to run prod, setting up a time with them, and then handholding them through running the right commands, because they weren&#x27;t sufficiently involved (or maybe one was, but the person you got today to run it wasn&#x27;t). Etc.
