The sad reality is that "very controlled, monitored and process oriented system" is just a nice wish as there are many things that just get into production and haven't been fully tested. As a matter of fact, I could send one script to validate and change it after validation and it will be deployed into production without problems.

So even with all the bureaucracy, the process is far from being perfect.

I wonder if we'll ever get to a point where changes are really controlled and validated without having to waste all that time to everyone involved (developers, dbas, bosses, etc).
