Is your design process a scientific method?

I have a weakness for science methods... I’ve mentioned it before. Dan Saffer just wrote about the design process and the scientific method. In short Saffer gives a good explanation why the design process is not a scientific method: a scientific process should lead to repeatable outcomes, while a design will (and should!) not. I agree.

UX professionals, as in other social / humanity professions, usually choose between a scientific view of their profession and a more humanity / quality / creative view. Social sciences are relatively new fields of science and for many years striving to prove that they deserve the “science” title. Postmodernism winds have changed it a little but still for the wide public the scientific title gives an integrity certificate to whatever people do. I know math & physics seems complicated to most people (and both are in many ways) but dealing with people is always more complicated and a bigger challenge in my view.  With no definite rules, no one paradigm, no outcome twice (even when you pursue the same process, as Saffer pointed out) you need more than “just” a scientific method to achieve a solution. Yes, I agree research will help, problem solving methods help too but none of these tells the full story of a design process, there is more into it.

So while some UX’ers invest in research, processes and methods other claim it is all about creativity, sketching and doing good. Is there a road in between? I hope so cause that is where I’m heading. Which way are you?

I believe this discussion merits a wider forum. For instance, I strongly believe in the merit of hard facts when certain, well-defined steps of the UCD process are concerned. For instance, testing results should be reproducable. If not, we could save the money for testing. If we just could rely on pure "gut feeling", sometimes disguised as "expertise", we just needs the UI designer, and no method, no lab, no testers.
On the other hand, during creation and concept stage, there is always space for imagination and design ideas. There are requirements, but they usually allow for several options. A good designer can recognize these options. But if in doubt what option is preferable, the designer needs to investigate and research. Just gut feeling will not be good enough.

Thank you Martin for your comment, I actually think we agree, but probably need to clarify a little more. I see UX as a combination of scientific work and something else which together gives it its special flavor…
Regarding reproducible testing, yes it should be, if you consider the options for testing as a final set. But give the requirements to a different team and you will most likely get some other options for testing. So if we look at the full cycle it (the design) probably cannot be repeated exactly. I agree it is not all, or even most gut feeling, but it is not all science too.
