A great painting has to be better than it has to be
This sounds like a paradox, but a great painting has to be better than it has to be. For example, when Leonardo painted the portrait of Ginevra de Benci in the National Gallery, he put a juniper bush behind her head. In it he carefully painted each individual leaf. Many painters might have thought, this is just something to put in the background to frame her head. No one will look that closely at it.
Not Leonardo. How hard he worked on part of a painting didn't depend at all on how closely he expected anyone to look at it. He was like Michael Jordan. Relentless.
Relentlessness wins because, in the aggregate, unseen details become visible. When people walk by the portrait of Ginevra de Benci, their attention is often immediately arrested by it, even before they look at the label and notice that it says Leonardo da Vinci. All those unseen details combine to produce something that's just stunning, like a thousand barely audible voices all singing in tune.
Great software, likewise, requires a fanatical devotion to beauty. If you look inside good software, you find that parts no one is ever supposed to see are beautiful too.
That which requires caring
Today's real world of technology is characterized by the dominance of prescriptive technologies.
The temptation to design more or less everything according to prescriptive and broken-up technologies is so strong that it is even applied to those tasks that should be conducted in a holistic way. Any tasks that require caring, whether for people or nature, any tasks that require immediate feedback and adjustment, are best done holistically. Such tasks cannot be planed, coordinated, and controlled the way prescriptive tasks must be.
Prescriptive technologies eliminate the occasions for decision-making and judgment in general and especially for the making of principled decisions. Any goal of the technology is incorporated a priori in the design and is not negotiable.
Jacked in
In digital design, products and services are frequently imagined and implemented placelessly: as if the consumer were jacked into The Matrix, and considering this product or that product from among an infinite set of choices at an infinitely-provisioned mercantile. The things we make are good, by this way of reasoning, if they fit the market’s demand.
Losing meaning
The people who’ve proven that they can make very good individual products with the radical focus of a spotlight seem to be pushed ever further from making good ecosystems.
Products are being made “consistent” with the application of so-called “design patterns,” and rather than bringing coherence to these various touch-points, the painting-on of interface standards and interaction patterns did something far less valuable.
Rote consistency, in the way many seem to be going about it (Material Design being just one example), is at odds with making things be good. It simplifies what needs to remain complex.
Always, when simplification is underway, meaning is being lost.
Penn Station
In the same way that physical architecture can affect a mind, so too can software. Slower, less reliable software is like Penn Station: Sure, you can catch a transfer from one train to another but the dreary lowness of the place, the lack of sunlight or sensible wayfinding will make you feel like a rat, truculent and worthless, and worse: You’ll acclimate to that feeling and accept it as a norm.
The Design of Design
A Book by Frederick P. Brooks, Jr.Visualizing Algorithms
An Article by Mike BostockManifesto for Agile Software Development
A DefinitionWe are uncovering better ways of developing software by doing it and helping others do it. Through this work we have come to value:
- Individuals and interactions over processes and tools
- Working software over comprehensive documentation
- Customer collaboration over contract negotiation
- Responding to change over following a plan
That is, while there is value in the items on the right, we value the items on the left more.

Ensuring Excellence
An Article by Marty Cagan…in so many of the best product companies there is an additional dimension that goes beyond individual empowered product teams, and even goes beyond achieving business results.
It has to do with ensuring a level of what I’ll refer to here as “excellence” although that is clearly a very ambiguous term.
Over the years, this concept has been referred to by many different names, always necessarily vague, but all striving to convey the same thing: “desirability,” “aha moments,” “wow factor,” “magic experiences,” or “customer delight,” to list just a few.
The concept is that an effective product that achieves results is critical, but sometimes we want to go even beyond that, to provide something special.
Maybe it’s because we believe this is needed to achieve the necessary value. Maybe it’s because the company has built its brand on inspiring customers.
Often this dimension shows up most clearly in product design, where functional, usable but uninspiring designs can often achieve our business results, but great design can propel us into this realm of the inspiring.
On online collaboration and our obligations as makers of software
An Essay by Baldur BjarnasonIs it the notetaking system that’s helping you think more clearly? Or is it the act of writing that forces you to clarify your thoughts?
Is it the complex interlinked web of notes that helps you get new ideas? Or is it all the reading you’re doing to fill that notetaking app bucket?
Is all of this notetaking work making you smarter? Or is it just indirectly forcing you into deliberate, goalless practice?
In Search of Organic Software
An Article by Pirijan KetheswaranTwo different kinds of farms can grow vegetables. One is a factory farm built for scale, and the other takes the time to grow more expensive but healthier plants without pesticides.
Will everyone appreciate the difference? Of course not, but the latter plants are labelled ‘organic’ to give us the information and the choice, so that those of us who do care can make better decisions.
So maybe we should have ‘organic’ software as well, made by companies that:
- Are not funded in such a way where the primary obligation of the company is to 🎡 chase funding rounds or get acquired (so bootstrapping, crowdfunding, grants, and angel investment are okay)
- Have a clear pricing page
- Disclose their sources of funding and sources of revenue
Reflections on Software Performance
An Article by Nelson Elhage- Performance is a feature
- Performance changes how users use software
- Performance needs effort throughout a project’s lifecycle
- Architecture strongly impacts performance
- Performance isn’t just about hot spots
- Performant foundations simplify architecture
…we underrate performance when designing and building software. We have become accustomed to casually giving up factors of two or ten or more with our choices of tools and libraries, without asking if the benefits are worth it.
Undoing the Toxic Dogmatism of Digital Design
An Essay by Lisa Angela- Design educators and industry leaders have never reached a consensus about what comprises a “good enough” foundational education for digital design.
- We do not properly retire methods (or ways of conducting them) that have been shown to be ineffective.
- Design team seniority levels are meaningless.
- We’ve collectively lost the safety (and subsequently the desire) to explore and fail.
- We afford well-known design leaders too much power to dictate how design is discussed and conducted.
- We have no ethical standards.
- Inclusive design and accessibility are afterthoughts — both in design education and in practice.
The things that you’re meant to do
A Quote by Josh WardleI used to work in Silicon Valley, and I’m aware of the things that, especially with games, you’re meant to do with people’s attention. You’re trying to capture as much of people’s attention as you can. So that involves things like endless play, or sending them push notifications, or asking them for sign-up information.
And philosophically, I enjoy doing the opposite of all those things, doing all the things that you are not meant to do, which I think has bizarrely had this effect where the game feels really human and just enjoyable. And that really resonates with where we’re at right now in the world and with COVID, and then also we’re trying to figure out, what is tech? What has tech become? I think that really resonates with people, and no ads—well, no monetization. People ask me a lot about these things, and it was like, I was literally just making a game for my partner, and I made some decisions that we would like.
I don’t believe in Zoom fatigue
An Article by Matt WebbIt’s not Zoom fatigue, it’s Zoom whiplash.
It’s a hunch. I can’t prove this.
The trick to get around this is to move smoothly up and down the gradient of social interaction intensity, never dropping below a basic floor of presence: the sense that there are other people in the same place as you.
Instead of having two modes, “in a call” and “on my own,” we need to think about multiple ways of being together which, minimally, could be:
- In a video call
- In an anteroom to a video call, hearing the sound of others
- In a doc together
- On my desktop but with the sense that colleagues are around
And the job of the designer is to ensure that their software ensures the existence of these different contexts, instead of having the binary on-a-call/not-on-a-call, and to design the transitions between them.
Spatial Software
An Article by John PalmerScales of cities, scales of software
An Article by Linus the SephistAmerican cities seem like a product of industrial processes where older European cities seem like a product of human processes. This is because most American cities were built after and alongside the car and the industrial revolution – the design of cities took into account what was easily possible, and that guided the shape and scale of everything.
Software has similar analogues. There are software codebases that feel much more industrially generated than hand written, and they’re usually written in automation-rich environments fitting into frameworks and other orchestrating code.
…But despite the availability of cars, I still much prefer the scale and ambiance of European, human-scale cities, because ultimately cities are places humans must inhabit and understand. In the same way, I still much prefer the scale and ambiance of hand-written codebases even in the presence of heavy programming tooling, because ultimately codebases are places humans must inhabit.
Driving engineers to an arbitrary date is a value destroying mistake
An Article by Gandalf HudlowWhat happens when you apply date pressure to software engineers working on high value software projects? The engineers will focus on delivering Something™ by the Date™! This fatal flaw results in delivery of a Something™ full of chaos and features that nobody really wants or needs.
How can we develop transformative tools for thought?
A Research Paper by Andy Matuschak & Michael NielsenConventional tech industry product practice will not produce deep enough subject matter insights to create transformative tools for thought.
...The aspiration is for any team serious about making transformative tools for thought. It’s to create a culture that combines the best parts of modern product practice with the best parts of the (very different) modern research culture. You need the insight-through-making loop to operate, whereby deep, original insights about the subject feed back to change and improve the system, and changes to the system result in deep, original insights about the subject.
Software Engineering as a Craft
An Article by Thomas WilsonThe decreasingly tangible product of code, i.e. that all we have are files on a hard-drive, may make it easy to forget that writing software produces a thing. If you produce a wonky chair or an overly long fork, it’s easy to see the quality of work was not great. By calling for a perception of software as a craft, we fight against that ability to forget or not notice the final quality of the product. You could watch two software engineers with different levels of experience, or in different domains, and it wouldn’t necessarily be so easy to guess which is which, at least from a distance.
So maybe there is something to be said for the value of software as a craft, for sometimes focusing on the practice of making better, or at least different, software just for the sake of it.

Software developers have stopped caring about reliability
An Article by Drew DeVaultOf all the principles of software engineering which has fallen by the wayside in the modern “move fast and break things” mentality of assholes modern software developers, reliability is perhaps the most neglected, along with its cousin, robustness. Almost all software that users encounter in
$CURRENTYEAR
is straight-up broken, and often badly.The Rise Of User-Hostile Software
An Essay by Den DelimarskyWe are truly living in an era of user-hostile software, and when I say “user-hostile” I mean it as “software that doesn’t really care about the needs of the user but rather about the needs of the developer.”
I personally do not know anyone who asked for an online account requirement before they can use a keyboard; however, some product lead somewhere decided that it’s important to better “understand the customer” and “maximize marketing reach” through some weekly “Hey, we have a new keyboard!” newsletter.
Minimum Awesome Product
An Article by Carlos BeneytoUsers are accustomed to a minimum of quality, and they expect that of all new products.
If our product does not [meet basic expectations of quality], people will automatically believe that it is a bad product and they will not take it seriously. It is not what they expect.
Hence my suggestion that the MVP has died and the MAP: Minimum Awesome Product was born.
Traditional companies are losing because they mismanage software engineers
An Article by Emma WattersonInnovation is messy, and frankly Anti-Steve [Jobs] can’t figure out why you wouldn’t just tell people the right thing to build and skip all the trial and error that comes with innovation. Anti-Steve and his board of directors that keep him in place fundamentally believe that they know what needs to be built. Or at least that they can hire the messiah that will come down off the mountain and tell everyone what to build. There is no such messiah.
Research, empathy, simplicity, speed

Here are four elements that I believe are the foundation of great digital products: Research, Empathy, Simplicity and Speed.
Craft and Material in Digital Design
An ArticleProduct Design Resources
A Reference Work by Brandon DornThings I‘ve read, people I‘ve tried to learn from, and things I‘ve done to become a better designer. This is an idiosyncratic list reflecting what has helped me along the way, rather than an exhaustive list of design classics.
Though the list leans toward theory — principles are more durable than technique — I offer a few ideas further down about how to practice design. It also leans toward information design, because the task of presenting rich, dense information in an accessible way is ultimately the task of any digital product.
Functional Prototyping. A Missed Opportunity in Web Design

Apps Getting Worse
An Article by Tim BrayToo often, a popular consumer app unexpectedly gets worse: Some combination of harder to use, missing features, and slower. At a time in history where software is significantly eating the world, this is nonsensical. It’s also damaging to the lives of the people who depend on these products.
...Maybe we ought to start promoting PMs who are willing to stand pat for an occasional release or three. Maybe we ought to fire all the consumer-product PMs. Maybe we ought to start including realistic customer-retraining-cost estimates in our product planning process.
We need to stop breaking the software people use. Everyone deserves better.
Feature parity
An ArticleWhilst Feature Parity often sounds like a reasonable proposition, we have learnt the hard way that people greatly underestimate the effort required, and thus misjudge the choice between this and the other alternatives. For example even just defining the 'as is' scope can be a huge effort, especially for legacy systems that have become core to the business.
Most legacy systems have 'bloated' over time, with many features unused by users (50% according to a 2014 Standish Group report) as new features have been added without the old ones being removed. Workarounds for past bugs and limitations have become 'must have' requirements for current business processes, with the way users work defined as much by the limitations of legacy as anything else. Rebuilding these features is not only waste it also represents a missed opportunity to build what is actually needed today. These systems were often defined 10 or 20 years ago within the constraints of previous generations of technology, it very rarely makes sense to replicate them 'as is'.
The return of fancy tools
An Article by Tom MacWrightTechnology is seeing a little return to complexity. Dreamweaver gave way to hand-coding websites, which is now leading into Webflow, which is a lot like Dreamweaver. Evernote give way to minimal Markdown notes, which are now becoming Notion, Coda, or Craft. Visual Studio was “disrupted” by Sublime Text and TextMate, which are now getting replaced by Visual Studio Code. JIRA was replaced by GitHub issues, which is getting outmoded by Linear. The pendulum swings back and forth, which isn’t a bad thing
On Design Engineering: I think I might be a design engineer...
An Article by Trys MudfordDesign engineering is the name for the discipline that finesses the overlap between design and engineering to speed delivery and idea validation. From prototyping to production-ready code, this function fast-tracks design decisions, mitigates risk, and establishes UI code quality. The design engineer’s work encapsulates the systems, workflows, and technology that empower designers and engineers to collaborate most effectively to optimise product development and innovation.
— Natalya ShelburneWebsites are not living rooms and other lessons for information architecture
An Essay by Sarah R. BarrettWhile there is a lot that IA can learn from actual architecture or city planning, websites aren’t buildings or cities, and they don’t have to work like them. Instead, they should be designed according to the same principles that people’s brains expect from physical experiences.
Software that nobody wants
An Article by Gandalf HudlowFinding value is the result of enabling individual and group-level discovery attempts. It's not the result of everyone following one leader's gut.
What just happened is a new software product/feature was created that no customer wanted. This happens way too often. In fact, most hyper important software projects that must be done by date certain or else, have deep flaws that cause some variation of this phenomenon, flaws that include:
- Not wanted - Company specified a solution to a problem that customers don't actually have
- No Rarity - Company is pursuing an iKnockoff of existing products. The market already has two scaled competitors with working solutions, customers naturally spend budget on products that are already successful to avoid risk
- Incorrect Packaging - Customers need a website, but the company created an iOS app instead
- Incorrect Pricing - Customers need SaaS pricing, but the company created a shrink wrapped, on-premise solution with CapEx and maintenance agreements instead

Clues for software design in how we sketch maps of cities
An Article by Matt WebbGiven there’s an explosion in software to accrete and organise knowledge, is the page model really the best approach?
Perhaps the building blocks shouldn’t be pages or blocks, but
neighbourhoods
roads
rooms and doors
landmarks.Or rather, as a knowledge base or wiki develops, it should - just like a real city - encourage its users to gravitate towards these different fundamental elements. A page that starts to function a little bit like a road should transform into a slick navigation element, available on all its linked pages. A page which is functioning like a landmark should start being visible from two hops away.
Fast Software, the Best Software
An Essay by Craig ModI love fast software. That is, software speedy both in function and interface. Software with minimal to no lag between wanting to activate or manipulate something and the thing happening. Lightness.
Software that’s speedy usually means it’s focused. Like a good tool, it often means that it’s simple, but that’s not necessarily true. Speed in software is probably the most valuable, least valued asset. To me, speedy software is the difference between an application smoothly integrating into your life, and one called upon with great reluctance. Fastness in software is like great margins in a book — makes you smile without necessarily knowing why.

Why Software is Slow and Shitty
An Article by Pirijan KetheswaranPlanning doesn't make for better software
A Fragment by Robin RendleMy own time in a Silicon Valley startup has proved this much to be true; planning doesn’t make for better software. In fact today our design systems team doesn’t have sprints, we don’t have tickets or a daily standup. Each day we come to work, figure out what’s the most important thing that we could be doing, and then we—gasp!—actually do it.
Watching so many other teams slowly flail about whilst they plan for quarter 3.2 of subplan A, whilst our team produces more work in a week than they all do combined in a quarter has been shocking to me.
After four years of working in a large startup, I know what I always assumed was true: you don’t need a plan to make a beautiful thing. You really don’t. In fact, there’s a point where overplanning can be a signal of inexperience and fear and bullshit. The scrum board and the sprints and the inane meetings each and every day are not how you build another Super Mario 64.
Instead all you have to do is hire smart people, trust them to do their best work, and then get the hell out of their way.
Figma's Engineering Values: Craftsmanship
An ArticleCraftsmanship is about thoughtfulness and care in the work we do. It means being deliberate about what we build and how possible it will be to maintain and extend in the future. A solution that will require revisiting in a month — because it’s not scaling, because it has a ton of bugs, because it doesn’t support all the use cases it needs to — is not useful to us and ultimately will generate pain for our users.
What we trade off by living this value is (sometimes) day-to-day speed. It’s easy to imagine an engineering team that emphasizes moving fast over keeping things stable and bug-free -- like a team building a product that isn’t responsible for important user data and doesn’t support anyone’s livelihood. But given the role the Figma product plays in the lives of our users, we feel it’s worth it to ensure we hold a high quality bar for them. And in the long run, being thoughtful about how we build often reduces the complexity of ongoing development and new features regardless.
On the "Building" of Software and Websites
An Essay by Dorian TaylorI’m beginning to suspect that software, and more conspicuously the Web, is fundamentally the wrong shape for the archetype of the construction project.
Yagni
A Definition by Martin FowlerYagni originally is an acronym that stands for "You Aren't Gonna Need It". It is a mantra from Extreme Programming that's often used generally in agile software teams. It's a statement that some capability we presume our software needs in the future should not be built now because "you aren't gonna need it".
The State of Agile Software in 2018
A Talk by Martin FowlerOn the surface, the world of agile software development is bright, since it is now mainstream. But the reality is troubling, because much of what is done is faux-agile, disregarding agile's values and principles. The three main challenges we should focus on are: fighting the Agile Industrial Complex and its habit of imposing process upon teams, raising the importance of technical excellence, and organizing our teams around products (rather than projects).

Like, just a post complaining that screens should be better
An Article by Matt WebbIt’s been 19 years since Pixar released Monsters, Inc. with all that CGI hair. Where are my hairy icons? Ones that get all long and knotted as the notifications number goes up.
Why can’t I feel my phone? I found that paper from 2010 (when I was complaining about keyboards) about using precision electrostatics to make artificial textures on touchscreens.
I should be able to run my thumb over my phone while it’s in my pocket and feel bumps for apps that want my attention. Touching an active element should feel rough. A scrollbar should *slip. Imagine the accessibility gains. But honestly I don’t even care if it’s useful: 1.5 billion smartphone screens are manufactured every year. For that number, I expect bells. I expect whistles.
The Design of Design
What's Wrong With This Model?
A ChapterDesign process models: A summary argument
- A formal design process model is needed, to help organize design work, to aid communication in and about projects, and for teaching.
- Having a visual, geometric representation of a design process model is crucial, for designers are spatial thinkers. They will most easily learn, think about, share, and talk in terms of a model with a clear geometric picture.
- The Rational Model of design occurs naturally to engineers.
- The linear, step-by-step Rational Model is highly misleading. It does not reflect what real designers do, or what the best design thinkers identify as the essence of the design process.
- The bad model matters. It has led to the too-early binding of requirements, leading in turn to bloated products and schedule/budget/performance disasters.
- The Rational Model has persisted in practice despite its inadequacies and plenty of cogent critiques. This is because of its seductive logical simplicity, and because builders and clients needs “contracts."
- Several alternative models have been proposed. I find Boehm’s Spiral Model the most promising. We need to keep developing it.
The spiral model
The spiral shape certainly suggests progress. It associates successive repetitions of the same activity. The geometric shape is easily understood and memorable. The model emphasizes prototyping, starting with user-interface prototypes and user testing long before an operational prototype is possible.
Since a development model is principally used by developers, I believe having it designer-centered is entirely appropriate. With Boehm and against Denning and Dragon, I advocate frequent but not continuous interaction with representative users, with successive prototypes as the vehicles.
I strongly believe that way forward is to embrace and develop the Spiral Model.
A grossly obese set of requirements
Who advocates in the requirements process for the product itself—its conceptual integrity, its efficiency, its economy, it’s robustness? Often, no one. As often, an architect or engineer who can offer only opinion based on taste and instinct, unbuttressed as yet by facts. For in a classical Waterfall Model product process, requirements are set before design is begun.
The result, of course, is a grossly obese set of requirements, the union of many wish lists, assembled without constraints. Usually, the list is neither prioritized nor weighted. The social forces in the committee forbid the painful conflicts occasioned by even weighting, much less prioritizing.
Requirements proliferation
Any attempt to formulate all possible requirements at the start of a project will fail and would cause considerable delays. — Pahl and Beitz, Engineering Design
As Project Manager, I had to reject the requirements document as totally impractical, and have a quite small team of architects, marketers, and implementers extract the essence.
Requirements proliferation must be fought, by both birth control and infanticide.
The architectural contracting model
It is the necessity for contracts, whether within an organization or between organizations, that forces the too-early binding of goals, requirements, constraints. The pressure for a complete and agreed-upon set of requirements run into the hard fact, that it is essentially impossible to specify any complete and accurate set of requirements for any complex system except in iterative interaction with the design process.
How have the centuries-old building design disciplines handled this perplexity? Fundamentally, by a quite different contracting model.
- The client develops a program, not a specification, for the building.
- He contracts with an architect, usually on an hourly or percentage basis, for services, not for a specified product.
- The architect elicits from the client, the users, and other stakeholders a more complete program, which does not pretend to be a rigid contractable product specification.
- The architect does a conceptual design that approximates the reconciliation of program and the constraints of budget, schedule, and code. This serves as a first prototype, to be conceptually tested by the stakeholders.
- After iteration, the architect performs design development, often producing more detailed drawings, a 3-D scale model, mockups, and so on. After stakeholder iteration, the architect produces construction drawings and specifications.
- The client uses these drawings and specifications to enter into a fixed-price contract for the product.
Notice how this long-evolved model separates the contract for design from the contract for construction. Even when both are performed by the same organization, this separation clarifies many things.
The rational model of design
Engineers seem to have a clear, if usually implicit, model of the process of design. It is usually an orderly model of an orderly process as the engineer conceives it.
The notion that the design process should be modeled as a systematic step-by-step process seems to have first developed in the German mechanical engineering community.
Herbert Simon independently argues for design as a search process in The Sciences of the Artificial. He was motivated to lay out a strictly rational model of design precisely because such a model was a necessary precursor to automating design. His model remains influential even if today we recognize the "wicked problem" of original design as one of the least promising candidates for AI.
In software engineering, Winston Royce independently introduced a seven-step Waterfall Model to bring order to the process. In fact, Royce introduced his waterfall as a straw man that he then argued against, but many people have cited and followed the straw man rather than his more sophisticated models. Even if ironically, Royce's seven-step model must be considered one of the foundational statements of the Rational Model of Design.
Design process models
Any systematization of the design process is a great step forward compared to "Let's just start coding, or building." It:
- Provides clear steps for planning a design project
- Furnishes clearly definable milestones
- Suggests project organization and staffing
- Helps communication within the design team
- Is readily teachable to novices, and tells novices facing their first design assignments where to begin.
The Rational Model in particular brings yet more advantages. The early explicit statement of goals, secondary desiderata, and constraints helps a team avoid wandering, and it breeds team unification on purposes. Planning the whole design process before starting coding or formal drawings avoids many troubles and much wasted effort. Casting the process as a systematic search of a design space broadens the horizon of the individual designers and lifts their eyes far beyond their previous personal experiences.
But the rational model is much too simplistic, even in Simon's richly developed version.
The dual ladder
The first task for growing designers, as opposed to managers, is to craft a proper career path for them, one whose compensation and sociological status reflect their true value to the creative enterprise. This is commonly called the dual ladder. It it easy to give corresponding salaries to corresponding rungs, but it requires strong proactive measures to give them equal prestige: equal offices, equal staff support, reverse-biased raises when duties change.
Why does the dual ladder need special attention? Perhaps because managers, being human, are inherently inclined to consider their own tasks more difficult and important than design and need to deliberately assess what makes creativity and innovation happen.
A platonic ideal
As the architecture design progressed, I observed what at first seemed quite strange. For the architecture team, the real System/360 was the Design Concept itself, a Platonic ideal computer. Those physical and electrical Model 50, Model 60, Model 70, and Model 90 things under construction out on the engineering floors were but Plato’s shadows of the real System/360. The real System/360’s most complete and faithful embodiment was not in silicon, copper, and steel, but in the prose and diagrams of IBM System/360 Principles of Operation, the programmer’s machine language manual.
I had a similar experience with the View/360 beach house. Its Design Concept came to be real long before any construction began. It persisted through many versions of drawings and cardboard models.
The design concept
Is there positive value to recognizing an invisible Design Concept as a real entity in design conversations? I think so.
First, great designs have conceptual integrity—unity, economy, clarity. They not only work, they delight, as Vitruvius first articulated. We use terms such as elegant, clean, beautiful to talk about bridges, sonatas, circuits, bicycles, computers, and iPhones. Recognizing the Design Concept as an entity helps us to seek its integrity in our own solo designs, to work together for it in team designs, and to teach it to our youth.
Second, talking frequently about the Design Concept as such vastly aids communication within a design team. Unity of concept is the goal; it is achieved only by much conversation.
Thus, moviemakers use storyboards to keep their design conversations focused on the Design Concept, rather than on implementation details.
The Idea
The design is thus the mental formulation, which Sayers calls “the Idea,” and it can be complete before any realization is begun. Mozart’s response to his father’s inquiry about an opera due to the duke in three weeks both stuns us and clarifies the concept.
For most human makers of things, the incompletenesses and inconsistencies of our ideas become clear only during implementation. Thus it is that writing, experimentation, “working out,” are essential disciplines for the theoretician.
The boldest decisions
In retrospect, many of the case studies have a striking common attribute: the boldest design decisions, whoever made them, have accounted for a high fraction of the goodness of the outcome. These bold decisions were made due sometimes to vision, sometimes to desperation. They were always gambles, requiring extra investment in hopes of getting a much better result.
Intuition and systems
Systematic design excluding intuition yields pedestrian follow-ons and knock-offs; intuitive design without system yields flawed fancies. How to weld intuition and systematic approach? How to grow as a designer? How to function in a design team?
