Next to a description of an artefact, plans for its production, and plans for its use, the product of a design project must always be a design proposal. There is the rare case where a design “speaks for itself”, but even in that instance, what that design says amounts to an argument that proposes the design’s actualization. And in arguing for a boss, client, or teacher, to make it like this, automatically means to not make it like that, or to leave the world as it is and keep making the same thing as before, or to make nothing new at all.
In practice, the goal and measure of success of such a proposal is that it persuades. In academic circles, we should instead be interested in whether the argument is any good in terms of its logic and evidentiary weight. Also in practice, however, those on the receiving end of a design proposal will want to judge how successfully the arguments offered actually justify a belief in the value of the design under consideration, and to poke through any rhetorical flourishes and salestalk that may be involved. In fact, I would argue that engineers –as opposed to those with sales and business titles– are under a moral obligation to strive for the same: an honest presentation of the merits of a design, accurate rather than merely giving the impression of accuracy. If “trust me, I’m an engineer” is to remain a valid request, we should strive to be trustworthy.
What is the logic of design proposals? What, exactly, are the claims that are made when designers present the results of their efforts? And how are and can these be justified?
Is the result of design always a proposal? Do designs published in academic journals fit this description?
At first glance, they don’t. Their message is more “Here is what we made. It’s really good/interesting/valuable/impressive.” But isn’t this the same as saying “This is how we should make these kinds of things for these kinds of situations.”? Or, “This is how we should solve this problem, or reach this goal.”?
