It depends on the persons perspective of engineering.
I do not agree for a few reasons, one being the statement that "if a problem is not solvable, its proponents believed, it is because the problem solver were not able to define the problem." I strongly disagree, someone may not be able to solve a problem simply because they lack the education, tools, or experience necessary not because they couldn't define it properly. Also, as we have talked about in class, the process is not always logical and in order, it can be messy and all over but that is okay.
A problem that that lacks definitive formulation, stopping roles, operations, and definitive solutions. The characteristics are 1) design problems are partly determined by explicit needs and constraints 2) a major part of design problems is underdetermined and 3) most parts of design problems can be considered undetermined.
One benefit is that it does not simply claim that engineering is complex; it also identifies how the complexity occurred and was managed. The ethnographical approach can describe the engineering design process realistically.
