In most significant decisions in gamedev you want art, design and engineering (at least - QA, audio, animation and a number of others as well) to be involved. Some people from one discipline may be versed enough in another to cover the role, but the role must still be present, or there will be pain and work thrown away later on. (incidentally, the ability to understand an issue from these multiple but interrelated angles is what makes experienced people so valuable in gamedev, and their constant loss to other less crazy industries so painful)
