Pixar's Braintrust has rules. First, feedback must be constructive – and about the project, not the person. Similarly, the filmmaker cannot be defensive or take criticism personally and must be ready to hear the truth. Second, the comments are suggestions, not prescriptions. There are no mandates, top-down or otherwise; the director is ultimately the one responsible for the movie and can take or leave solutions offered. Third, candid feedback is not a “gotcha” but must come from a place of empathy. It helps that the directors have often already gone through the process themselves. Praise and appreciation, especially for the director's vision and ambition, are doled out in heaping measures.

Braintrusts – groups of people with a shared agenda who offer candid feedback to their peers – are subject to individual personalities and chemistries. In other words, they can easily go off the rails if the process isn't well led. To be effective, managers have to monitor dynamics continually over time. It helps enormously if people respect each other's expertise and trust each other's opinions. Pixar director Andrew Stanton offers advice for how to choose people for an effective feedback group. They must, he says, “make you think smarter and put lots of solutions on the table in a short amount of time.” Stanton's point about having people around who make us “think smarter” gets to the heart of why psychological safety is essential to innovation and progress. We can only think smarter if others in the room speak their minds.

There is some dispute about when, exactly, the Braintrust came into being. That’s because it developed organically, growing out of the rare working relationship among the five men who led and edited the production of Toy Story - John Lasseter, Andrew Stanton, Pete Docter, Lee Unkrich, and Joe Ranft. From Pixar’s earliest days, this quintet gave us a solid example of what a highly functional working group should be. They were funny, focused, smart, and relentlessly candid with each other. Most crucially, they never allowed themselves to be thwarted by the kinds of structural or personal issues that can render meaningful communication in a group setting impossible. It was only when we rallied to fix Toy Story 2, coming together to solve a crisis, that the “Braintrust” entered the Pixar lexicon as an official term.

There will always be plenty to be afraid of, especially when you are doing something new. Trusting others doesn’t mean that they won’t make mistakes. It means that if they do (or if you do), you trust they will act to help solve it. Fear can be created quickly; trust can’t. Leaders must demonstrate their trustworthiness, over time, through their actions - and the best way to do that is by responding well to failure. The Braintrust and various groups within Pixar have gone through difficult times together, solved problems together, and that is how they’ve built up trust in each other. Be patient. Be authentic. And be consistent. The trust will come.

This concept, completely counter to what we believed and practiced at Pixar, could only result in an inferior product, so we made an announcement: From that day forward, there would be no more mandatory notes.
Disney Animation’s directors needed a feedback system that worked, so we immediately set about helping them create their own version of the Braintrust - a safe arena in which to solicit and interpret candid responses to developing projects. (This was made easier by the fact that they already liked and trusted each other. Even before our arrival, we were told, they’d formed their own under-the-radar group called the Story Trust, but the lack of management understanding for that concept had prevented it from evolving into a coherent forum.)
