I am about to have my students start asking questions of each other that come from differing perspectives. During critiques of their projects I will have groups of 4 or 5 students ask questions from a political perspective, another group ask questions from an economic perspective, and another ask questions from a manufacturing perspective etc...
Although we are primarily dealing with product design I think it will give the students pause to think on a broader basis about what they do.
I will let you know if it works or not.
