CD Projekt RED - Killing Your Darlings - Speak @ GDC Europe 2012
At GDC Europe 2012, Marek Zimak, gameplay producer and Maciej Szczesnik from CD Project RED gave a speak on how the studio has a method for killing the developers' favorite features.
A quote on how this is done:
CD Projekt Red uses a set of internal documents that the studio's employees all have access to. Using these documents, developers can describe their features and the rest of the staff evaluates them. In some cases, staffers even apply numerical values to a proposed feature, with the final "score" affecting the likelihood that a feature will make it into the game. The overarching idea is to fully analyze the risk of a feature and the consequences of implementing it.
