This is a great article that breaks down some of the principles that Pixar has put into place to ensure their ongoing success. Granted, there are a lot of other things that tie into their success, such as the broader culture that they have established, but if you think about these principles - how many are in place where you work?
1. When it sucks, say so.
2. Defend your opinion, then 'hit play quickly'.
3. Look upstream for the source of the problem.
4. Match the medium to the message
5. Hire for excellence.
