The vanishing designer An Article by Chuánqí Sun uxdesign.cc Visionary designers have lost their conceptual integrity to an industrial complex optimized for consensus, predictability, and short-term business gain. The rise of customer-obsession mantra and data-driven culture cultivated a generation of designers who only take risk-free and success-guaranteed steps towards the inevitable local maxima of design monotony.

Don’t Be an Ostrich An Essay by Chuánqí Sun medium.com You just handed off a major redesign. Three months of research, twenty-seven major revisions, and hundreds cups of coffee have all culminated in this pinnacle of glory. It’s finally done! Except it’s not. It’s not, even after you have answered every single question the developers have about your red-line. It’s not, even after you have addressed all the technical constraints developers encountered during the implementation. It’s not, even after you meticulously documented all the patterns and styles into a library for reference and reuse. It’s not, because neither you nor the developers have talked to a real user. At the bottom of your heart, you are secretly wishing: My design looks great on paper, so let’s keep it on paper. You are an ostrich. Post-occupancy evaluation
A case against "pixel perfect" design An Essay by Chuánqí Sun uxdesign.cc I feel the push for the “pixel perfect” design has largely overlooked many of its practical, social, and ethical implications. We are working against the grain of the woodGood design is practical design

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.
