Found this neat article by Jason Tammemägi on the 8 things that an animator should know, he starts with:
"1 – BE YOUR OWN QUALITY CONTROL
We all have our own internal quality control. Working in any hierarchy can cause us to disengage our own quality control and rely on the next person up the chain. That is not how you get the best results. Get a scene to its absolute best first. When your animation director or director is looking at a scene that is already excellent, we can all get it from excellent to magical together. Taking a scene from stinky to acceptable isn’t quite as rewarding for anyone. So be your own quality control. It is just about working at it until it’s great."
