Here's a nice quote from Jony Ive to support your point Much of the design process is a conversation, a back-and-forth as we walk around the tables and play with the models. [Steve Jobs] doesn't like to read complex drawings. He wants to see and feel a model. He's right. I get surprised when we make a model and then realize it's rubbish, even though based on CAD renderings it looked great. He loves coming in here because it's calm and gentle. It's a paradise if you're a visual person. There are no formal design reviews, so there are no huge decision points. Instead, we can make the decisions fluid. Since we iterate every day and never have dumb-ass presentations, we don't run into major disagreements.
