I think a lot of this comes from the history of Undercurrent, its various children, and other vaguely similar agencies such as IDEO and Idea Couture. What you have are design agencies who move slowly up the innovation ladder from products, to strategy, and then to the fundamentals of the organization itself.
Usually the foundation of this practice is design thinking, whose customer-centric paradigm touches on similar strands in the Lean Startup methodology.
After travelling the world for a while I find I have the money and time to continue studies in a way that would further my growing personal purpose of making work not suck. But my own research is more along along the lines of sociology than psychology, and this is making it difficult for me to know what kind of skills organizational design agencies are looking for. (I’ll take suggestions.)
Agencies like Idea Couture, however, have a place for anthropological or sociological ethnographic studies of culture. Along with the psychologist studying how the workplace affects individuals, I’d really like to see more talk about how the social structures of the workplace mimic those of society. I understand why consultants have to in practice place innovation and productivity first, but really there should be a larger voice to workplace democracy, even if we can only state it explicitly in theory.
