Values vs. strengths There is sometimes a conflict between a person's values and his or her strengths. What one does well – even very well and successfully – may not fit with one's value system. In that case, the work may not appear to be worth devoting one's lift to (or even a substantial portion thereof). Values are and should be the ultimate test. Peter F.

The mirror test In the early years of this century, the most highly respected diplomat of all the great powers was the german ambassador in London. He was clearly destined for great things...yet in 1906 he abruptly resigned rather than preside over a dinner given by the diplomatic corps for Edward VII. The king was a notorious womanizer and made it clear what kind of dinner he wanted. The ambassador is reported to have said, "I refuse to see a pimp in the mirror in the morning when I shave." This is the mirror test. Ethics requires that you ask yourself, What kind of person do I want to see in the mirror in the morning? Peter F. Drucker, Managing Oneself ethicsvalues
The receiving end At times it helps to rephrase an observation in line with a perspective from the receiving end of technology. When my colleagues in the field of cold-water engineering speak of "ice-infested waters", I am tempted to think of "rig-infested oceans". Language is a fine barometer of values and priorities. As such it deserves careful attention. Ursula M. Franklin, The Real World of Technology valuesenvironmentlanguage
If we didn’t live to work A Fragment by Charlie Warzel warzel.substack.com When you talk to people who reject the modern notion of a career, many of them say the same thing: They crave more balance, less precarity, and better pay. They also, crucially, want to work. What’s profound about the career rejectionists is that their guiding questions are simple. What if work didn’t make you feel awful? What would life be like if we didn’t live to work? What do workers and employers actually owe each other? What if we structured our work lives around a different idea of success? workvalues

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.
