Engineering Maintenance Quotes

Systems program building is an entropy-decreasing process, hence inherently metastable. Program maintenance is an entropy-increasing process, and even its most skillful execution only delays the subsidence of the system into unfixable obsolescence.

Motivation of this sort, once it catches hold, is a ferocious force, and in the gradeless, degreeless institution where our student would find himself, he wouldn’t stop with rote engineering information.

But what really matters is what's under the hood, and without continued attention to routine maintenance and repairs, it isn't long before the same old engine spoils the new ride.

A basic principle of data processing teaches the folly of trying to maintain independent files in synchonism.

The application of this knife, the division of the world into parts and the building of this structure, is something everybody does. All the time we are aware of millions of things around us - these changing shapes, these burning hills, the sound of the engine, the feel of the throttle, each rock and weed and fence post and piece of debris beside the road - aware of these things but not really conscious of them unless there is something unusual or unless they reflect something we are predisposed to see. We could not possibly be conscious of these things and remember all of them because our mind would be so full of useless details we would be unable to think. From all this awareness we must select, and what we select and calls consciousness is never the same as the awareness because the process of selection mutates it. We take a handful of sand from the endless landscape of awareness around us and call that handful of sand the world.

The best line of work for me would be roadside sprite. I'd live quietly by a dust-covered track that people never came across unless they took a wrong turn, and I'd offer the baffled travelers lemonade and sandwiches, maybe even fix their engines if they asked nicely (I'd have used my solitude to read extensively on matters of car maintenance). Then the travelers would go on their way, relaxed and refreshed, and they'd forget they'd ever met me. That's the ideal meeting... once upon a time, only once, unexpectedly, then never again.

The sooner we associate long hours and multitasking with incompetence and carelessness the better. The next time you hear boasts of executives pulling an all-nighter or holding conference calls in their cars, be sure to offer your condolences; it's grim being stuck in sweatshops run by managers too ignorant to understand productivity and risk. Working people like this is as smart as running your factory without maintenance. In manufacturing and engineering businesses, everyone learns that the top priority is asset integrity: protecting the machinery on which the business depends. In knowledge-based economies, that machinery is the mind.

That's all the motorcycle is, a system of concepts worked out in steel. There's no part in it, no shape in it, that is not out of someone's mind [...] I've noticed that people who have never worked with steel have trouble seeing this—that the motorcycle is primarily a mental phenomenon. They associate metal with given shapes—pipes, rods, girders, tools, parts—all of them fixed and inviolable., and think of it as primarily physical. But a person who does machining or foundry work or forger work or welding sees "steel" as having no shape at all. Steel can be any shape you want if you are skilled enough, and any shape but the one you want if you are not. Shapes, like this tappet, are what you arrive at, what you give to the steel. Steel has no more shape than this old pile of dirt on the engine here. These shapes are all of someone's mind. That's important to see. The steel? Hell, even the steel is out of someone's mind. There's no steel in nature. Anyone from the Bronze Age could have told you that. All nature has is a potential for steel. There's nothing else there.

Emma is the engine of this home, the person who propels it forward, keeps everyone fed and clothed and healthy and happy—and yet she’s entirely alone within it, and getting lonelier with every item ticked off her checklist. This is what it comes down to: the flat-out invisible drudgery of family maintenance, the vanishing of personality as everyone else’s accrues.

I’m about to sharpen up the engine a little.

The tapping of her foot seemed less like agitation and more like an expression of optimism and energy, a hunger for things. Its regularity seemed almost practical, as though this foot pedaled the engine that powered the girl’s world and she was simply keeping it going, pushing it forward, an impatient maintenance.

Keep innovation and maintenance together. A frequent practice is to spin up a new team to innovate while existing teams are bogged down in maintenance. I’ve historically done this myself, but I’ve moved toward innovating within existing teams.5 This requires very deliberate decision-making and some bravery, but in exchange you’ll get higher morale and a culture of learning, and will avoid creating a two-tiered class system of innovators and maintainers.

Program maintenance involves no cleaning, lubrication, or repair of deterioration. It consists chiefly of changes that repair design defects. Much more often than with hardware, these changes include added functions. Usually they are visible to the user. The total cost of maintaining a widely used program is typically 40 percent or more of the cost of developing it. Surprisingly, this cost is strongly affected by the number of users. More users find more bugs.

I asked a nurse for dental floss and was told that I am not allowed dental floss. Apparently dental floss can be used for several functions besides the maintenance of healthy gums. These apparently include self-harm. When instructed that I was not permitted dental floss because of “risks it raises associated with suicide” I envisioned a noose made entirely of floss. Realizing such a noose would require a dramatic amount of floss to effectively uphold any human person, I brought it to the attention of a nurse. “I don’t believe that even the most practiced engineers could fashion any functioning noose out of a single container of floss,” I say. “People use it to cut themselves,” she explained. “Oh,” I replied. I had just about come to terms with the no-floss rule until the hospital, in a flagrant display of disrespect for its patients, chose to serve us corn on the cob for lunch. “Are you aware that we are not allowed dental floss?” I yelled at the nurse bringing me the corn. I then threw the corn violently from my plate into the nearest wall.

Our development team of 100 engineers drinks a lot of coffee… Equipping each floor with new coffee stations would cost $15,000, plus additional ongoing fees for supplies and maintenance. At 10 minutes a day per person traveling down to the break room for coffee and back, our engineering department spends 80 hours a week getting caffeine. New coffee makers would pay for themselves within weeks; afterward, they’d make money for the company. Our current system acts as if we’ve hired 2 full-time engineers just to walk back and forth from their offices to the break room, and their hall banter isn’t even close to West Wing quality.

Don’t ask me to sketch the circuitry of a suit; I can’t. But I understand that some very good concert violinists can’t build a violin, either. I can do field maintenance and field repairs and check off the three hundred and forty-seven items from „cold“ to ready to wear, and that’s all a dumb M. I. is expected to do. But if my suit gets really sick, I call the doctor—a doctor of science (electromechanical engineering) who is a staff Naval officer, usually a lieutenant (read „captain“ for our ranks), and is part of the ship’s company of the troop transport—or who is reluctantly assigned to a regimental headquarters at Camp Currie, a fate-worse-thandeath to a Navy man.

A classical understanding sees the world primarily as underlying form itself. A romantic understanding sees it primarily in terms of immediate appearance. If you were to show an engine or a mechanical drawing or electronic schematic to a romantic it is unlikely he would see much of interest in it. It has no appeal because the reality he sees is its surface. Dull, complex lists of names, lines and numbers. Nothing interesting. But if you were to show the same blueprint or schematic or give the same description to a classical person he might look at it and then become fascinated by it because he sees that within the lines and shapes and symbols is a tremendous richness of underlying form.

At Corbis, looking at the reasons why we worked on too many things at once was a revealing exercise. The CFO wanted to implement a new financial system. The SVP of Global Marketing wanted to blah, blah, blah. The VP of Media Services also wanted blah, blah, blah. The head of Sales wanted blah, blah, blah, blah. And they all wanted everything now. The resulting business priorities clashed all the way down the hierarchy and that was just the business side of the house. On the engineering side, not only did we need to implement all the business requests, we also had our own internal improvements to make and maintenance work to do. Furthermore, we still had to be available to drop everything when production issues occurred—like it or not, production comes first.

Quality is the response of an organism to its environment’ [he used this example because his chief questioners seemed to see things in terms of stimulus-response behavior theory]. An amoeba, placed on a plate of water with a drip of dilute sulfuric acid placed nearby, will pull away from the acid (I think). If it could speak the amoeba, without knowing anything about sulfuric acid, could say, ‘This environment has poor quality.’ If it had a nervous system it would act in a much more complex way to overcome the poor quality of the environment. It would seek analogues, that is, images and symbols from its previous experience, to define the unpleasant nature of its new environment and thus ‘understand’ it. “In our highly complex organic state we advanced organisms respond to our environment with an invention of many marvelous analogues. We invent earth and heavens, trees, stones and oceans, gods, music, arts, language, philosophy, engineering, civilization and science. We call these analogues reality. And they are reality. We mesmerize our children in the name of truth into knowing that they are reality. We throw anyone who does not accept these analogues into an insane asylum. But that which causes us to invent the analogues is Quality. Quality is the continuing stimulus which our environment puts upon us to create the world in which we live. All of it. Every last bit of it. “Now, to take that which has caused us to create the world, and include it within the world we have created, is clearly impossible. That is why Quality cannot be defined. If we do define it we are defining something less than Quality itself.” I remember this fragment more vividly than any of the others, possibly because it is the most important of all. When he wrote it he felt momentary fright and was about to strike out the words “All of it.

As humans we spend our time seeking big, meaningful experiences. So the afterlife may surprise you when your body wears out. We expand back into what we really are—which is, by Earth standards, enormous. We stand ten thousand kilometers tall in each of nine dimensions and live with others like us in a celestial commune. When we reawaken in these, our true bodies, we immediately begin to notice that our gargantuan colleagues suffer a deep sense of angst. Our job is the maintenance and upholding of the cosmos. Universal collapse is imminent, and we engineer wormholes to act as structural support. We labor relentlessly on the edge of cosmic disaster. If we don’t execute our jobs flawlessly, the universe will re-collapse. Ours is complex, intricate, and important work. After three centuries of this toil, we have the option to take a vacation. We all choose the same destination: we project ourselves into lower-dimensional creatures. We project ourselves into the tiny, delicate, three-dimensional bodies that we call humans, and we are born onto the resort we call Earth. The idea, on such vacations, is to capture small experiences. On the Earth, we care only about our immediate surroundings. We watch comedy movies. We drink alcohol and enjoy music. We form relationships, fight, break up, and start again. When we’re in a human body, we don’t care about universal collapse—instead, we care only about a meeting of the eyes, a glimpse of bare flesh, the caressing tones of a loved voice, joy, love, light, the orientation of a house plant, the shade of a paint stroke, the arrangement of hair. Those are good vacations that we take on Earth, replete with our little dramas and fusses. The mental relaxation is unspeakably precious to us. And when we’re forced to leave by the wearing out of those delicate little bodies, it is not uncommon to see us lying prostrate in the breeze of the solar winds, tools in hand, looking out into the cosmos, wet-eyed, searching for meaninglessness.

In 2012, we tried to put a stop to this with rules mitigating churn: infrastructure teams must do the work to move their internal users to new versions themselves or do the update in place, in backward-compatible fashion. This policy, which we’ve called the “Churn Rule,” scales better: dependent projects are no longer spending progressively greater effort just to keep up. We’ve also learned that having a dedicated group of experts execute the change scales better than asking for more maintenance effort from every user: experts spend some time learning the whole problem in depth and then apply that expertise to every subproblem. Forcing users to respond to churn means that every affected team does a worse job ramping up, solves their immediate problem, and then throws away that now-useless knowledge. Expertise scales better.

Valujet flight 592 crashed after takeoff from Miami airport because oxygen generators in its cargo hold caught fire. The generators had been loaded onto the airplane by employees of a maintenance contractor, who were subsequently prosecuted. The editor of Aviation Week and Space Technology “strongly believed the failure of SabreTech employees to put caps on oxygen generators constituted willful negligence that led to the killing of 110 passengers and crew. Prosecutors were right to bring charges. There has to be some fear that not doing one’s job correctly could lead to prosecution.”13 But holding individuals accountable by prosecuting them misses the point. It shortcuts the need to learn fundamental lessons, if it acknowledges that fundamental lessons are there to be learned in the first place. In the SabreTech case, maintenance employees inhabited a world of boss-men and sudden firings, and that did not supply safety caps for expired oxygen generators. The airline may have been as inexperienced and under as much financial pressure as people in the maintenance organization supporting it. It was also a world of language difficulties—not only because many were Spanish speakers in an environment of English engineering language: “Here is what really happened. Nearly 600 people logged work time against the three Valujet airplanes in SabreTech’s Miami hangar; of them 72 workers logged 910 hours across several weeks against the job of replacing the ‘expired’ oxygen generators—those at the end of their approved lives. According to the supplied Valujet work card 0069, the second step of the seven-step process was: ‘If the generator has not been expended install shipping cap on the firing pin.’ This required a gang of hard-pressed mechanics to draw a distinction between canisters that were ‘expired’, meaning the ones they were removing, and canisters that were not ‘expended’, meaning the same ones, loaded and ready to fire, on which they were now expected to put nonexistent caps. Also involved were canisters which were expired and expended, and others which were not expired but were expended. And then, of course, there was the simpler thing—a set of new replacement canisters, which were both unexpended and unexpired.”14 These were conditions that existed long before the Valujet accident, and that exist in many places today. Fear of prosecution stifles the flow of information about such conditions. And information is the prime asset that makes a safety culture work. A flow of information earlier could in fact have told the bad news. It could have revealed these features of people’s tasks and tools; these longstanding vulnerabilities that form the stuff that accidents are made of. It would have shown how ‘human error’ is inextricably connected to how the work is done, with what resources, and under what circumstances and pressures.

I flew home with Iran Air, which gave me six and a half hours to truly appreciate the impact of the international sanctions first hand. The scratchy seat fabric, cigarette-burned plastic washbasins and whiff of engine oil throughout the cabin reminded me of late seventies coach travel, which was probably the last time these planes had had a facelift. I tried to convince myself that Iran Air had prioritised the maintenance of engines and safety features over the interior decor but I wasn’t convinced, especially when the seatbelt refused to budge. The in-flight entertainment had certainly been spared an upgrade, consisting of one small television at the front of the plane showing repeat screenings of a gentle propaganda film featuring chador-clad women gazing at waterfalls and flowers with an appropriately tinkly soundtrack. The stewardesses’ outfits were suitably dreary too. Reflecting Iran Air’s status as the national carrier of the Islamic Republic, they were of course modest to the point of unflattering, with not a single glimpse of neck or hair visible beneath the military style cap and hijab. As we took off, I examined my fellow passengers. Nobody was praying and as soon as we were airborne, every female passenger removed her headscarf without ceremony.

But it’s still really clear to me that many of Rand’s ideas are prevalent in culture, especially American culture, and especially in engineering and technology: they prioritize making things over caregiving and maintenance, the new and novel over what’s sustained, ideas and artifacts that can deliver a profit over activities that need an ongoing commitment of money and other resources, and individualism over acting collectively.
