What the document is called in the end is secondary. The important point in my opinion is that MIT sat together and discussed and also wrote down what they want, how they want it and likely (as an outcome of their discussion) also have an understanding where there are areas to negotiate/compromise on are. Or in other words, they prepared themselves for the negotiations so they know when to be firm or angry.
