When users never use the features they asked for
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.
Time-based analytics
An Article by Ryan SingerAnalytics apps don't tell you much about usage behavior. You might be able to see how many users performed an event, or how many times they did it. But none of the analytics packages out there are good at showing you how often people do things. Are they using to-dos once a week? Every day? Only signing into the app once a month but happily paying for years?
Time matters. You can't understand usage without time.
What happens to user experience in a minimum viable product?
An Article by Ryan Singer"Feature complexity is like surface area and quality of execution is like height. I want a base level of quality execution across all features. Whenever I commit to building or expanding a feature, I'm committing to a baseline of effort on the user experience."
There’s a distinction to make: The set of features you choose to build is one thing. The level you choose to execute at is another. You can decide whether or not to include a feature like ‘reset password’. But if you decide to do it, you should live up to a basic standard of execution on the experience side.
Features can be different sizes with more or less complexity, but quality of experience should be constant across all features. That constant quality of experience is what gives your customers trust. It demonstrates to them that whatever you build, you build well.
August short No. 2: Glass
An Article by Riccardo MoriGlass looks and feels perfectly tailored to my photo sharing needs and expectations. For me it’s even better than pre-Facebook Instagram in the sense that it pushes me to select and share what I think are good photos (same as it happens with Flickr), rather than making me obsess with getting ‘the Instagram shot’ at all costs every day or multiple times in a day. It doesn’t cheapen photography like Instagram has done for years.
That’s why I hope Glass’s founders/developers will resist feature creep. Resist user objections like: I don’t think Glass is offering that much for the subscription price they’re asking. There are a lot of people who will gladly pay for having a cleaner, simpler, focused experience.
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'.
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
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.
Not Just a New Feature; a New Compact
A Fragment by Jorge ArangoMy sense is that Slack’s teams think of themselves as adding ‘features’ to a ‘product,’ instead of as stewards of a place where people work.
Understanding the Kano Model
An Article by Jared SpoolThe horizontal axis represents the investment the organization makes. As investment increases, the organization spends more resources on improving the quality (remember, Noriaka was a quality guy at heart) or adding new capabilities.
The vertical dimension represents the satisfaction of the user, moving from an extreme negative of frustration to an extreme positive of delight. (Neutral satisfaction being neither frustrated nor delighted is in the middle of the axis.)
It’s against the backdrop of these two axes that we see how the Kano Model works. It shows us there are three forces at work, which we can use to predict our users’ satisfaction with the investment we make.
Doing It Right
An Article by Brad FrostDoing it right requires a different pace of working and a much broader thought process than “ok, let’s get this thing out the door.” Which is super tough because most workplaces place a huge emphasis on getting things out the door, and fast. Little agile tickets that are expected to be completed in micro sprints to me seem to be antithetical to doing it right.
The Web is Industrialized and I Helped Industrialize It
An Article by Dave RupertIn our cultural obsession with billionaire entrepreneurs we laud new features more than the maintenance and incrementalism work of making old features better and more accessible. Maintenance looks like red minus signs in the spreadsheet. New features look like green plus signs. New features look better on our LinkedIn profiles. New features have that pizzazz, baby.
When gardening, the building of planters and initial planting is a very short process. The majority of your time is spent nurturing and monitoring growth. I personally feel the struggle between maintainer work and new shiny feature work. I enjoy that new feature smell but I know that my day-to-day is more like a janitor on a boat mopping up someone else’s barf. In terms of metaphors, the gardening metaphor is certainly better, and it acknowledges that design and development still tend to be more creative endeavors.
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".

An EssayIconography
It is understandable that those students who must work from reproductions of works of art are usually more interested in iconography than in the more subtle questions of technique and quality, but it is regrettable that technical ignorance should so frequently prevent art historians from considering the whole experience of the artist.
Understanding technique
Technique is an essential aspect of any work of art from a trivial trinket to the greatest painting, and some specialized study of it is essential to full appreciation.
Though museum labels and catalogs refer to materials and processes — “bronze,” “fresco,” “parcel gilt,” “tempera,” “lacquer on wood,” and so on — they usually display only superficial attention to the essential details of the artist’s technique.
Bells
Most Japanese bells when hung still have on them one or more rough lines obviously arising in horizontal mold joints. These lines are not removed in fettling the bell, and they seem to be regarded not as defects but rather as a reminder of the reality of the founder’s interaction with his materials. One is reminded of the ceramics that are most treasured in Japan which usually have some unexpected tool marks or irregularity resulting from a kiln mishap.
Nearer to the surface
If in the following I overemphasize the Orient, this is simply because in the Far East the properties of materials are a little nearer to the surface, a little more consciously a part of what the artist is trying to show. The naturalistic aspects of Oriental philosophy encourage a sensitivity to the quality of materials — or is it the inverse, that an early enjoyment of stone, wood, clay, and fiber gave rise to the philosopher’s perception of the soul in all natural things comparable to man himself? Westerners tend to override materials, usually in ignorance, but sometimes proudly as a tour de force.
The drop press
The virtue of thin sheet metal in giving the greatest glitter for a grain of gold was exploited in the earliest days of metallurgy. However, before the days of rolled sheet and drawn wire, most metal objects were made by hammering and were basically three-dimensional in form.
[In contrast] look at the simple drop press — it’s unmodulated blow striking in a single direction symbolizes much of nineteenth-century mechanized production. To make multiple stampings, stacks of very thin metal sheets were superimposed under the hammer, and the final profile with moderately high relief was gradually achieved as finished sheets were removed from the bottom and new ones added at the top.
When the drop press was used to shape large areas of thin sheet metal, the aesthetic qualities of the surface became divorced from the underlying substance, and decoration became independent of the body needed to support it. In any object there is a natural relationship between the surface and the bulk, that is, between its one-, two-, and three-dimensional aspects. The fakery involved in applying gold or silver playing on a solid copper object is quite different from the deception of an ornately stamped piece of thin sheet brass. Compare a magnificent ormolu furniture fitting or even a gilded plaster picture frame with a cheap lamp base embossed in thin sheet brass. In the former, the surface is simply and honestly applied for its optical effect alone; in the latter the fakery is fundamental for it is dimensionally misleading.
Big things and little things
It is hardly possible that human beings could have decided logically that they needed to develop language in order to communicate with each other before they had experienced pleasurable interactive communal activities like singing and dancing. Aesthetic curiosity has been central to both genetic and cultural evolution.
All big things grow from little things, but new little things will be destroyed by their environment unless they are cherished for reasons more like love than purpose.
What's the difference?
I well remember an occasion in 1962 when in a remote Iranian village I asked a blacksmith famous for his superior penknives to tell me the difference between iron and steel. “What’s the difference?” he replied. “What’s the difference between an oak tree and a willow — they have different natures and one must adapt to them.” He did not accept the suggestion that some material absorbed from the fire’s charcoal might have something to do with it, and he would not have understood a word of any lecture I could have given him on diffusion, crystal structure, and phase transformations; yet he could make a good knife and I could not.
The scale of human experience
It is the scale of human experience, from which thought and imagination take off, and to which they must return.
The edifice from which they came
A list of types of bricks used in the Hagia Sophia may help one to build an interesting brick wall, but it poorly suggests the great edifice from which they came.
The interplay of pattern and texture
Some of the more enjoyable surfaces (for example, the grain of a fine mahogany table top or a Japanese sword) have an interplay between pattern and texture which, though two-dimensional, suggests the unseen internal three-dimensional array.
Resonances
The resonances arising in workmanship are often very subtle. The fact that the material itself guides the tool differently in different processes of working introduces changes in the overall relationship of curvatures. The smooth curves of surfaces approaching the edge of a jade axe that come about from innumerable abrasive particles moving against a slightly yielding and mechanically unconstrained backing would seem incongruous if other surfaces or outlines were present that had come from cleavage or from the geometric motions of a machine. These could be produced easily enough, but the eye would not establish larger resonances among them.
Fine arts and decorative arts
The fine arts are conscious and essentially individual in tradition.
The quantitative and economic aspects of the decorative arts, on the other hand, make them intrinsically repetitive. Because of this, their aesthetic qualities have a very intimate relationship to the technology of materials, and their design is thereby basically affected.
In addition to the qualitative need for repetitive detail in design, the decorative arts have a quantitative requirement, namely the imperative of covering large areas or making large numbers of individual objects.
Replication
Consider also the development of mass-production methods involving the casting of molten metals. Though the finest castings were made individually by the lost-wax process, the majority of casting from the earliest days have been designed expressly to facilitate molding. As with punches and dies, most foundry processes have the characteristic that the careful work of the master designer is involved only once, whereafter replication takes over.
Reproduction
The success of a mechanic’s, or a machine’s, reproduction of a thing depends on his, or its, sensitivity to whatever qualities are important, just as the skill of the designer lies in the proper appreciation of surface qualities in terms of structure and shape variation that come from the intended means of production.
The inner nature of material
The work of an artist in getting the details that he wants is greatly facilitated if he selects a material whose inner nature makes it want to take the desired shape.
The idea grows as they work
As they work, the experience of the material under the artist's fingers subtly interacts with the idea in their mind to give the finished work some quality that was rarely fully anticipated. A few artists seem to have such a feeling for their materials that the prevision needs little modification; most say that the idea grows as they work experimentally.
True artistry
The best of all examples of a satisfactory art form based upon the inner nature of a metal is provided by Japanese swords.
Our perception of beauty seems to involve the interaction of several patterns having origin and significance at many different levels of space, time, matter, and spirit. In the Japanese sword blade there is heterogeneity in both the macrostructure and the microstructure. The manner of forging, the heat treatment, and the final polishing operation are all uniquely Japanese techniques, and all make necessary contributions to the final quality of the blades. The shape along would be simplistic form; the forged texture of the steel without heat treatment would at best faintly echo the beauty of grained wood; the outlines of the quench-hardened zone at the edge would be sharp and uninteresting if it depended only on the control of cooling rate during quenching; and the polish would be uniform glitter if the metal were homogeneous. With true artistry all these are made to interact.
Simple variations of the parts
Symmetry, indeed, has been grossly overemphasized in both art and science: its main value is in giving meaning to its absence, dissymmetry, without which there could be no hierarchy.
The eye is repulsed by complexity if no order is detected, but it can be delighted by repetition, translation, rotation, reflection, magnification, and other simple variations of the parts.
