What we are
Client work leads. The rest comes out of it.
The engagements are where the problems come from, the research is how the method stays arguable, and a product is what a problem becomes the third time it turns up.
Client work
Engagements where the hard part is technical, taken on directly rather than staffed out.
Research
The method written down far enough to be disagreed with, rather than the conclusion on its own.
Products
The problems that stopped being one client's, built out far enough to stand on their own.
