ELI5: When an animation studio like Pixar has multiple dozens of people, all with their own styles, working on a project, how do they keep everything uniform?

Usually in animation we have model sheets and motion bibles (terms vary from studio to studio) that tell us how each character expresses themselves, reacts, and moves. Everything from how they look over one shoulder, how they smile, where their centre of balance is, what they do when surprised, and so on. 

This helps keep all the work uniform.
