Problem Solving
The solution of the age
What the problem is
You can't look a big problem too directly in the eye
Everything works both ways
The kind of problem a city is
The problem of the house has not yet been stated
Clinging to ideas
A good question is better than a brilliant answer
A normal wooden pencil
Each fascinating crisis
You are agreeing to make a Thing
How to be a genius
Old solutions
As something we have never seen before
The technology shelf
Details first
Each pattern is a rule
When all you have is a hammer

Framing vs. Shaping
Learning to walk through walls
An Article by David R. MacIverI have a running joke that one of the most useful things I do when coaching or consulting is to say to people “Yes, that does sound like a problem. Have you tried solving it?”
Part of why this is a joke is that actually most of the useful work happens prior to the point - the hard part is actually articulating what is going wrong well enough that it seems like a soluble problem - but there is genuinely something useful about this, because often it feels people are looking for permission.
Without the external prompt, solving their problem is not something they noticed that they were allowed to do.
Delight in the imperfect
An Article by David R. MacIverI think part of the difficulty in allowing ourselves to properly delight in the imperfect, comes from conflating delighting in something with wanting it to happen. This isn’t the case. You can appreciate something as it exists while acknowledging its problems. You can see that a fire is beautiful without becoming a pyromaniac, and you can appreciate the absurdity of your political situation without thinking it’s good.
Even if a delight in the imperfect causes you to want more imperfection in your life (and it should), there is no shortage of imperfection to seek out. The imperfect is not scarce, it’s abundant. If you find imperfection delightful, you will never be short of things that delight you, even if you fix any given problem. Solving problems and smoothing out imperfections doesn’t remove the source of delight, it merely opens up new vistas for it. You could give yourself over totally to delight in the imperfect and never run out of things to explore, even without creating your own.
The Nature of Product
An Article by Marty CaganToo many product managers and product designers want to spend all their time in problem discovery, and not get their hands dirty in solution discovery – the whole nonsense of “product managers are responsible for the what and not the how.”
The Feynman Algorithm
A Definition- Write down the problem.
- Think real hard.
- Write down the solution.
The fastest way to learn something is to do something
An Article by David R. MacIverSuppose you have a problem to solve. What do you do?
Well, you sit down and think real hard, and after extensive and careful planning you try the well thought out and rigorous solution that you have thought up. Right?
No, wrong! Bad.
The correct thing to do when you have a problem is:
- Think for a short amount of time.
- Make sure it is safe to try things.
- Try something you think will work.
- Observe the result. If you succeeded, yay you solved the problem! If it didn't work, think about what that means for the nature of the problem and try again.
Scott and Scurvy
An Essay by Maciej Cegłowski…one of the simplest of diseases managed to utterly confound us for so long, at the cost of millions of lives, even after we had stumbled across an unequivocal cure. It makes you wonder how many incurable ailments of the modern world—depression, autism, hypertension, obesity—will turn out to have equally simple solutions, once we are able to see them in the correct light. What will we be slapping our foreheads about sixty years from now, wondering how we missed something so obvious?
Class 1 / Class 2 Problems
An Article by Kevin KellyThere are two classes of problems caused by new technology. Class 1 problems are due to it not working perfectly. Class 2 problems are due to it working perfectly.
...Class 1 problems arise early and they are easy to imagine. Usually market forces will solve them. You could say, most Class 1 problems are solved along the way as they rush to become Class 2 problems. Class 2 problems are much harder to solve because they require more than just the invisible hand of the market to overcome them.
...Class 1 problems are caused by technology that is not perfect, and are solved by the marketplace. Class 2 problems are caused by technology that is perfect, and must be solved by extra-market forces such as cultural norms, regulation, and social imagination.
Adding is favoured over subtracting in problem solving
A Research PaperHow would you change this structure so that you could put a masonry brick on top of it without crushing the figurine, bearing in mind that each block added costs 10 cents? If you are like most participants in a study reported by Adams et al. in Nature, you would add pillars to better support the roof. But a simpler (and cheaper) solution would be to remove the existing pillar, and let the roof simply rest on the base.
A series of problem-solving experiments reveal that people are more likely to consider solutions that add features than solutions that remove them, even when removing features is more efficient.
Do not propose solutions
A Quote“Do not propose solutions until the problem has been discussed as thoroughly as possible without suggesting any.
I have often used this edict with groups I have led—particularly when they face a very tough problem, which is when group members are most apt to propose solutions immediately.”
— Norman R.F. Maier
What we have known since long
A Quote by Ludwig WittgensteinThe problems are solved, not by giving new information, but by arranging what we have known since long.
Infrastructure: A Guide to the Industrial Landscape
Savage, hostile, and cruel
Some may find puzzling or distasteful the parallel I am drawing between the study of nature and the study of technology. After all, nature is good and good for you, whereas everyone knows that technology is ugly, evil, and dangerous.
A few centuries ago—say, on the American western frontier—a quite different view prevailed. Nature was seen as savage, hostile, cruel. Mountains and forests were barriers, not refuges. The lights of civilization were a comforting sight. We took our charter from the book of Genesis, which grants mankind dominion over the beasts, and felt it was both our entitlement and our duty to tame the wilderness, fell the trees, plow the land, and dam the rivers.
Nature undisturbed
My chief aim is simply to describe and explain the technological fabric of society, not to judge whether it is good or bad, beautiful or ugly. And yet I would not argue that technology is neutral or value-free. Quite the contrary: I suggest that the signs of human presence are the only elements of the landscape that have and moral or aesthetic significance at all. In nature undisturbed, a desert is not better or worse than a forest or a swamp; there is simply no scale on which to rank such things unless it is a human scale of utility or beauty. Only when people intervene in nature is there any question of right or wrong, better or worse.
The raw materials of society
A big hole in the ground: This is where most of the raw materials of an industrial society come from. To appreciate the scale of this excavation, note that the bright blue object on a shelf near the center of the image is a Porta Potti.
The dragline
A dragline is the largest of the machines used to strip away the overburden and mine the ore layer at an open-cast mine. A bucketload for this particular dragline, one of the world's largest, is 220 cubic yards. Note the school bus, which would easily fit in the bucket.
Dark satanic steel
When poet William Blake wrote of "dark satanic mills", he couldn't have been looking at a steel mill because there were none in 1804. Nevertheless, when I visit a steel mill, Blake's phrase always comes to mind. With the heat and the pounding noise, the dust and smoke, and the red glow against the night sky, it's hard not to see these places as infernal. And yet the process of making steel also produces some of the most hauntingly beautiful images found anywhere in the world of industry.
Strength from both mass and form
Hoover Dam has the shape of an arch dam, but it is actually a hybrid structure, gathering strength from both mass and form. The dam is often ranked as one of the most exquisite of all engineered structures. It is fitted to its site so well that the gnarly canyon wall looks like an organic growth engulfing the mass of concrete.
Warmed by the afternoon sun
Textbooks on water-system engineering state that supply mains are generally installed on the north side of the street in the Northern Hemisphere and on the south side in the Southern Hemisphere, so that the sun will warm them. In both hemispheres they are supposed to be on the east side of north-south streets, on the premise that the afternoon sun is warmer than the morning sun.
Trompe l'oeil fantasies
In residential neighborhoods some sewage-pumping stations are trompe l'oeil fantasies, dressed up to look like the split-level or colonial houses that surround them. If you look closely, it's not hard to spot these disguised pumphouses: the heavy-duty power connections, the big ventilating fans, and the diesel generator in the backyard are all tip-offs. Furthermore, the windows are often fakes, with sash and shutters adorning a blank wall.
Quaker Square Inn
The modernist architect Le Corbusier was an admirer of American grain elevators, suggesting that their regularity and modularity could serve as a model for other kinds of buildings. At least one later architect took the suggestion seriously. The Quaker Square Inn in Akron, Ohio, occupies the shell of a former elevator. If you're in town for the night, you can rent a round room in one of the silos.
A metropolis for hydrocarbons
An oil refinery suggests the image of a metropolis for hydrocarbons, the pipe manifolds like expressways, the distillation towers like skyscrapers.
A haunting, syncopated music
"Rappers" on the roof of the electrostatic precipitator knock the accumulated dust free, letting it fall into the storage hopper. Each rapper is the size and shape of a baseball bat. Inside is an electromagnet that pulls a steel plunger upward, then allows it to fall again, producing a sharp knock. The rappers are energized at seemingly random intervals, producing a haunting, syncopated music. (The rhythm seemed more modern jazz than rap.)
Safety cut rope axe man
In the first nuclear reactor, constructed by Enrico Fermi in 1942 under the bleachers of the University of Chicago football stadium, the control rods were held up by a manila rope. A man with an axe was told to cut the rope if the reactor got out of hand. This "safety cut rope axe man" is supposedly the origin of the term SCRAM for an emergency shutdown procedure.
Pylons
Not all the towers along a transmission line are identical. Look closely at a tower where the line makes a sharp turn and you will likely find it is wider and beefier than other towers along the route. The added strength and weight are needed to resist the unbalanced pull of the conductors, which might overturn an ordinary tower. These special towers are called deviation or angle towers.
The transmission-line tower everybody knows is an Erector Set latticework of steel girders and diagonal braces. The techniques for designing and building these towers are the same ones used in constructing steel bridge trusses or crane booms. The individual pieces can be made cheaply from rolled steel and then bolted together on the site. This last point is more important than it might seem: transporting a fully assembled tower 100 feet tall is an awkward and expensive business.
Color coding
Telephone wires erupt in a multicolor cascade in a ground-level, pedestal-type splice case on a city street.
Dividing the set of 10 colors into two contrasting groups of 5 allows for exactly 25 combinations with one color from each group; thus, each pair in a bundle can be uniquely colored. A similar color code is applied to the ribbons that bind together all the pairs in a bundle, and to those of the superbundles. The result is highly festive! A specific wire might be identified as the blue-red conductor within the orange-black bundle within the brown-yellow superbundle.
The Iridium System
Several Low-Earth-Orbit (LEO) networks were proposed, but only one got off the ground: the Iridium system. The original Iridium proposal called for a "constellation" of 77 satellites, which gave the plan its name: the element iridium has atomic number 77, meaning that an iridium atom has 77 orbiting electrons. Before the satellites were launched, the constellation was scaled back to 66 active satellites, but no one wanted to change the name to Dysprosium.
Roads to nowhere
Among real-estate developers, straight lines and right angles went out of fashion sometime in the middle of the twentieth century. If you look at a town or a residential neighborhood laid out since then, you are more likely to find sinuous, serpentine roads—whether or not the topography offers any excuse for such curves. Many of these roads go nowhere: they are loops that bring you back to where you started, or they are cul-de-sacs. Making it easy to find your way through the network of streets is obviously not a high priority. This is an interesting development in urban geography: having redesigned the city to accommodate the automobile, we now search for ways to discourage people from driving on the streets.
A gradual refinement
The steel rail is an artifact whose form has been carefully optimized. This gradual refinement of the design was done not by a single brilliant engineer but by more than a century of industrial evolution. The rail was never meant to be an object of beauty, but its cross section has all the elegance of fine typography.
Hyperart: U.S. Rail
The steepest grade on U.S. main-line track is at the small town of Saluda, on a Norfolk Southern route between Spartanburg, South Carolina, and Asheville, North Carolina. The grade goes on for three miles at a slope of 4 or 5 percent. Trains have not been running on the line since 2001, but the tracks are still maintained.
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.
Routine design
When we think of bridges, it is the dramatic and monumental long spans that come to mind first, especially the lithe suspension bridges such as the Golden Gate and the pure geometric arches such as Sydney Harbour. But the majority of bridges are not such spectacular structures. Most of them are ordinary overpasses, with spans of 30 or 40 feet, carrying roadways or rails across other thoroughfares or over small streams. You see such bridges by the dozen on any drive down the Interstate. They may be lacking in glamour, but they are more representative of a bridge builder's art.
The engineering and construction of girder bridges are pretty routine these days, but the bridges are not quite standard items you order from a catalogue. The girders, whether of steel or concrete, are custom-build for each bridge, then trucked to the site and hoisted into place with a crane. The designer still has scope for variation and creativity, and it shows out on the highways: some overpasses are prettier than others.
No Smoking
What's that big electrical cord that also connects the ship to the dock? It's not a power cord to run machinery aboard ship; it's a grounding strap, to prevent sparks from static electricity. Something else you're sure to notice on a tanker is a big warning sign about the fire hazard. Frederick Allen, the editor of American Heritage of Invention & Technology, has remarked that all tankers seem to be named No Smoking.
Port furniture
All the miscellaneous fittings and fixtures on wharves and piers and elsewhere in nautical neighborhoods are known by the charming term port furniture.
The mirror-image economy
When we enter the world of refuse and waste, we cross over into a mirror-image economy. In the "normal" world, we pay to acquire things; on the other side of the looking glass, we pay to get rid of them. Junk isn't merely worthless; it has negative value.
A chemical engineer once told me about a recent improvement in a manufacturing process; by fine-tuning a chemical synthesis he had increased the yield of a certain commodity from 98 percent to 99 percent. I congratulated him, but I couldn't help remarking that this seemed like a rather paltry improvement. "Ah, you miss the important point," he said. "The amount of waste goes from 2 percent down to 1 percent. It's cut in half. We save tremendously on disposal costs."
NIMBY, BANANA, NOPE
Waste-disposal facilities of all kinds—landfills, incinerators, even transfer stations—are sure bets for generating the NIMBY response: not in my backyard. In its most cynical form, NIMBY is the attitude of citizens who acknowledge the need for a facility, somewhere, but who oppose a plan for building it simply because the selected site is too close to their own property. But opposition to landfills and many other kinds of development goes well beyond cynical NIMBY. Another catch phrase for this phenomenon is BANANA: build absolutely nothing anywhere near anybody. Or else it's NOPE: not on planet earth.
Creations of human artifice
In the twenty-first century, the question most of us ask when disaster strikes is not "How could God let that happen?" but "Who screwed up?" This is a salutary development: We take responsibility for the world we live in. Whether or not our world is the best of all possible worlds, it is a world we have made for ourselves. We live in an engineered landscape, on an engineered planet. Our cities and farms, our dwellings and vehicles, our power plans and communication networks—these are all creations of human artifice. If we don't like it here, we have only ourselves to blame.
What kind of world it's going to be
The wonderful thing about living in a world of our own creation is that we get to choose what kind of world it's going to be—at least in principle. But the promise is meaningful only if a broad enough "we" can be engaged in the process. At present, mechanisms and democratic institutions for making collective decisions about the deployment of technology are hopelessly cumbersome. How can anyone make a sensible choice without being able to weigh one alternative against another?
