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.

Your greatest challenge as a leader, then, is to honor each person’s legitimate fear of the unknown and, at the same time, to turn that fear into spiritedness. We, your followers, like the comfort of where we stand, yet know that the flow of events is pulling us inexorably into the unknown. So when we find something, anything, however slight, that lessens our uncertainty, we cling on for dear life.

If the crew is confused, then their leader is, too.
When this happens, we must act. To know when to act, we much watch carefully for signs that a movie is stuck. Here is one: A Braintrust meeting will occur, notes will be given, and
three months later, the movie will come back essentially unchanged. That is not okay. You
may say, “Wait a minute - I thought you just said the directors didn’t have to obey the notes!”
They don’t. But directors must find ways to address problems that are raised by the group
because the Braintrust represents the audience; when they are confused or otherwise
dissatisfied, there’s a good chance moviegoers will be too. The implication of being director-
led is that the director must lead.

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.)
