About Pixar, I really like the way they focus mainly in the story above everything else (difficulties, the interest of showing-off their skills, etc), and they also remain interested on transmitting the escence and characteristics that are particular of each of their characters in a story.
They also take risks and they make sure to do whatever it is needed in order to transmit their stroy, also they don't change things just because they are too difficult; they truly care about the story and everyone from the outside respect them for doing so, we all know Pixar won't deliver crap.
Another thing is that they hired their employees based mostly in their passion to do what they are good for (and what they like to do: their jobs), and that is also why they are the bests at it, and they continuously improve their works, projects and results.
As Bird says as a last comment "they nurture my story", its what really defines how Pixar works.
