Hi V.D. I would align myself with design thinking (small d, small t). Some of my basic thoughts on design thinking are in my article, Design thinking, unboxed. As implied by that article, I am concerned about reducing design thinking to a toolbox of methods, which is how some folks apply design thinking. “Design science” is a bit different, I think, and depending on how it is applied can become a kind of design Darwinism. The way I would put it is that design science if fine if you use designers to come up with the hypotheses and do not box them in by limiting the range of solutions they can consider. Does that make any sense?
