Visual versus Text are just means to an end. What matters is how you apply the given form within a method or process. A nice example of where hand code struggled and a visual language within the constructs of a formal method succeeded is the V22 Osprey compared to the BA609 Tiltrotor. The Navy struggles to maintain the V22 and the vehicle has a total of around 40 deaths attributed to it. While the BA609 has far fewer operational hours, it also is more rigorously tested. http://www.mathworks.com/videos/bell-helicopter-ensures-a-flawless-first-flight-78718.html http://www.mathworks.com/videos/bell-helicopter-ensures-a-fl... There are other notable examples of Model Based Design being more appropriate for large complex, mission critical, systems; Toyota's Prius, Curiosity, Dreamliner, etc.
