The argument carried on in a sphere We need not allow ourselves to be abashed by any suggestion that the old metaphors are out of date and ought to be superseded. We have only to remember that they are, and always were, metaphors, and that they are still “living” metaphors so long as we use them to interpret direct experience. Metaphors only become dead when the metaphor is substituted for the experience, and the argument carried on in a sphere of abstraction without being at every point related to life. Dorothy Sayers, The Mind of the Maker metaphor
Only in terms of other things No legislation could prevent the making of verbal pictures: God walks in the garden, He stretches out His arm, His voice shakes the cedars, His eyelids try the children of men. To forbid the making of pictures about God would be to forbid thinking about God at all, for man is so made that he has no way to think except in pictures. But continually, throughout the history of the Jewish-Christian Church, the voice of warning has been raised against the power of the picture-makers: “God is a spirit”, “without body, parts or passions”; He is pure being, “I AM THAT I AM”. The fact is, that all language about everything is analogical; we think in a series of metaphors. We can explain nothing in terms of itself, but only in terms of other things.

A renaming of the already named A true metaphor is a swift and violent twisting of language, A renaming of the already named. It's meant to expire in a sudden flash of light And to reveal—in that burst of illumination— A correspondence that must be literally accurate.

The strange familiar and the familiar strange The problem solver, when confronted with a new and yet unsolved problem, overlays the structure of the unsolved problem with an apparently similar problem with which he or she is experienced. Making the strange familiar and the familiar strange are also principally based on the use of analogy. Peter G. Rowe, Design Thinking metaphoranalogy
An emblem of friendship Bridges make connections; they bring people together—a role that has made them a traditional emblem of friendship. Consider the town of Mostar in Bosnia-Herzegovina. When fighting between ethnic factions broke out there in the 1990s, nothing symbolized the social disintegration more clearly than the destruction of a sixteenth-century stone-arch bridge that had linked the two parts of the town on opposite banks of the Neretva River. And the emblem of efforts to heal the divisions is a rebuilt bridge, opened with fireworks and fanfare in July of 2004.

Metaphors We Web By An Essay by Maggie Appleton maggieappleton.com As George Lakoff and Mark Johnson made clear in their touchstone book Metaphors We Live By, metaphors are the basis of all human thought and reasoning. The metaphors we use to speak about the web are not simply linguistic trivia – they determine how we understand it on a fundamental level. It determines what we think the web is capable of, what risks, opportunities, and challenges it poses. Which means the metaphors we use to think about the web profoundly influence what we think the web is, what we think we can do with it, and how we might change or evolve it. …Out of all of these metaphors [for the web], the two most enduring are paper and physical space.

What's wrong with the rational model We Don’t Really Know the Goal When We Start We Usually Don’t Know the Decision Tree – We Discover It as We Go The Nodes Are Really Not Design Decisions, but Tentative Complete Designs The Goodness Function Cannot be Evaluated Incrementally The Desiderata and Their Weightings Keep Changing The Constraints Keep Changing Changing constraintsDeciding what to designThe situation talks back
Deciding what to design We Don’t Really Know the Goal When We Start The most serious model shortcoming is that the designer often has a vague, incompletely specified goal, or primary objective. In such cases, the hardest part of design is deciding what to design. I came to realize that the most useful service I was performing for my client was helping him decide what he really wanted. Today, we recognize that rapid prototyping is an essential tool for formulating precise requirements. Not only is the design process iterative; the design-goal-setting process is itself iterative. Knowing complete product requirements up front is a quite rare exception, not the norm. Therefore, goal iteration must be considered an inherent part of the design process. What's wrong with the rational model iteration
Evaluating goodness The Goodness Function Cannot be Evaluated Incrementally The Rational Model assumes that design involves a search of the decision tree, and that at every node, one can evaluate the goodness function of several downward branches. In fact, one cannot in general do this without exploring all the downward branches to all their leaves, which is possible in principle, but leads to a combinatorial explosion of alternatives in practice. What's wrong with the rational model
Changing constraints The Constraints Keep Changing The explicit listing of known constraints in the design program helps here. The designer can periodically scan the list, asking, “Can this constraint now be removed because the world has changed? Can it be entirely circumvented by working outside the design space?” What's wrong with the rational model constraints
They just don't work that way Perhaps the most devastating critique of the Rational Model, although perhaps the hardest to prove, is that most experienced designers just don’t work that way. “Conventional wisdom about problem-solving seems often to be contradicted by the behavior of expert designers. Empirical studies of design activity have frequently found ‘intuitive’ features of design ability to be the most effective and relevant to the intrinsic nature of design. Some aspects of design theory, however, have tried to develop counter-intuitive models and prescriptions for design behavior.” — Nigel Cross
We must outgrow it Why all this fuss about the process model? Does the model we and others use to think about our design process really affect our designing itself? I believe it does. I believe our inadequate model and following it slavishly lead to fat, cumbersome, over-features products and also to schedule, budget, and performance disasters. The Rational Model, in any of its forms, leads us to demand up-front statements of design requirements. It leads us to believe that such can be formulated. It leads us to make contracts with one another on the basis of enshrined ignorance. A more realistic process model would make design work more efficient, obviating many arguments with clients and much rework. The Waterfall Model is wrong and harmful; we must outgrow it.
