I get a little worked up when I see network designers describing our craft as an ‘art.’ I understand where the thought comes from; there is certainly a level of creativity required to arrive at an optimal network design for a given set of constraints and business challenges. It is nevertheless my opinion that we are working within a science, not an art. The key differentiator is whether we can judge one network design to be superior to another. With the traditional arts, it not objectively possible to say one song/painting/movie is ‘better’ than another. We can measure them on various points (Rotten Tomatoes [link] scores for movies, sale price for paintings, etc), but how any one individual perceives an artist’s creation is not open to debate. I like Dumb & Dumber more than Casablanca, and no amount of objective information is going to change my mind!
