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".
Product vs. Feature Teams
An Article by Marty CaganThis article is certain to upset many people.
Thermal Delight in Architecture
Our thermal environment is as rich in cultural associations as our visual, acoustic, olfactory, and tactile environments. This book explores the potential for using thermal qualities as an expressive element in building design.
Until quite recently, building technology and design has favored high-energy-consuming mechanical methods of neutralizing the thermal environment. It has not responded to the various ways that people use, remember, and care about the thermal environment and how they associate their thermal sense with their other senses. Not only is thermal symbolism now obsolete but the modern emphasis on central heating systems and air conditioning and hermetically sealed buildings has actually damaged our thermal coping and sensing mechanisms.
The Cinderella of architecture
An analogy might be drawn with the use of light quality as a design element, truly a venerable old architectural tradition. The light quality—direct, indirect, natural, artificial, diffuse, dappled, focused—can be subtly manipulated in the design of a space in order to achieve the desired effect.
Thermal qualities might also be included in the architect's initial conception and could influence all phases of design. Instead, thermal conditions are commonly standardized with the use of modern mechanical systems that can be specified, installed, and left to function independently of the overall design concept.
Indeed, environmental control systems tend to be treated rather like the Cinderella of architecture; given only the plainest clothes to wear, they are relegated to a back room to do the drudgery that maintains the elegant life-style of the other sisters: light, form, structure, and so forth.
Two thermal archetypes
The hearth, a refuge of dry warmth from a cold world, and the oasis, a preserve of coolness and moisture in a desert wilderness.
Sonorisms III
One way not to be there (without dying).
"Yes, we have felt happy and alive together."
The Finnish word loyly, meaning "the steam which rises from the stones" originally signified spirit, or even life.
The tradition of the great shade tree.
Anasazi dwellings
The Anasazi Indians of the southwestern United States were remarkably clever in choosing the sites for their cliff dwellings. They invariably chose locations shaded in the summer by an overhanging ledge of the cliff, but exposed to full sun all winter long. With their backs to the cliff, the dwellings were protected from the winter winds and also took advantage of the thermal mass of the earth to moderate the temperature flux.
Migration within buildings
Many peoples of North Africa migrate within their buildings in both daily and seasonal patterns to take advantage of the various microclimates the buildings create.
Fascination with control
Fascination with this potential for control of our environment has prompted the invention of mechanical systems that have made natural thermal strategies seem obsolete by comparison.
The notion of a thermal optimum persists
There is an underlying assumption that the best thermal environment never needs to be noticed, and that once an objectively "comfortable" thermal environment has been provided, all of our thermal needs will have been met. The use of all of our extremely sophisticated environmental control systems is directed to this one end—to produce standard comfort zone conditions.
A simple pleasure that comes from just using it
People have a sense of warmth and coolness, a thermal sense like sight or smell, although it is not normally counted in the traditional list of our five senses.
As with all our other senses, there seems to be a simple pleasure that comes from just using it, letting it provide us with bits of information about the world around, using it to explore and learn, or just to notice.
There is a basic difference, however, between our thermal sense and all of our other senses. When our thermal sensors tell us an object is cold, that object is already making us colder. If, on the other hand, I look at a red object it won't make me grow redder, nor will touching a bump object make me bumpy.
Their opposites close at hand
We should note that all of these places of thermal extremes (Finnish saunas, Japanese hot baths, American beaches and mountains) have their opposites close at hand. There are possibly two reasons for having the extremes right next to each other.
The first is physiological: the availability of extremes ensures that we can move from one to the other to maintain a thermal balance.
The second might be termed aesthetic: the experience of each extreme is made more acute by contrast to the other.
Substitutes for the thermal experience
Such clues from other senses can become so strongly associated with a sense of coolness or warmth that they can occasionally substitute for the thermal experience itself. For example, the taste of mint seems refreshing and cool regardless of what temperature it is. Similarly, the pressure of heavy blankets conveys a feeling of warmth quite independent of their actual thermal qualities.
The totality of its sensory stimulation
Perhaps the human fascination with fire stems from the totality of its sensory stimulation. The fire gives a flickering and glowing light, ever moving, ever changing. It crackles and hisses and fills the room with the smells of smoke and wood and perhaps even food. It penetrates us with its warmth. Every sense is stimulated and all of their associated modes of perception, such as memory and an awareness of time, are also brought into play, focused on the one experience of the fire. Together they create such an intense feeling of reality, of the "here and nowness" of the moment, that the fire becomes completely captivating.
We need an object for our affections
We need an object for our affections, something identifiable on which to focus attention. But in a typical office building, to what can we attribute the all-pervasive comfort of 70ºF, 50% relative humidity? Most likely, we would simply take it all for granted. When thermal comfort is a constant condition, constant in both space and time, it becomes so abstract that it loses its potential to focus attention.
The Skylid
The louvers automatically open to let solar radiation in when the sun shines and close in the evening to prevent radiant heat loss, controlled and driven by the shifting weight of freon.
We look into the greenhouse and watch the Skylids closing automatically, one by one and in no particular order, and we are aware of the hot air rising, cold air settling. They remind us that the earth is turning and the day is ending.
Retained as a quality
Thermal information is not differentiated in our memory; rather it is retained as a quality, or underlying tone, associated with the whole experience of the place. It contributes to our sense of the particular personality, or spirit, that we identify with that place. In remembering the spirit of a place, we can anticipate that if we return, we will have the same sense of comfort or relaxation as before.
Thermal aediculae
The inglenook, the gazebo, and the porch swing also have strong definitions of their spaces. They are each a bit like a little house set off for a special thermal purpose. They might be termed "thermal aediculae". Although the term aedicula is most often used in conjunction with a sacred or ceremonial little house, it can also be used to describe any diminutive structure used to mark a place as special.
Summerson contends that there is a basic human "fascination of the minitature shelter." Perhaps this is because the aedicula intensifies ones experience of the place by working someone like a caricature. By reducing some things in scale, it exaggerates the importance of other things, most especially the size of a person in relation to the space.
At a uniformly comfortable termperature
In America our tendency has been to get away from thermal conditions as a determinant of behavior. Instead, we have used our technology to keep entire living and working complexes at a uniformly comfortable temperature. As a result, our spatial habits have become diffused, and activities that were once localized by thermal conditions have spread out over a whole house or building. We forget, unless a system breaks down, that such wide-ranging use of space is extremely dependent upon the available heating and cooling equipment.
For their own concealed passion
Sharing the experience of a pleasant thermal setting may add an extra bonus to courtship. The gentle and cooling breeze of the southern porch swing provided a happy excuse for a couple to sit quietly together. A more technological version might be seen in the type of car that the teenagers of the 1950s considered ideal for a hot date—the convertible. Slightly more erotic, perhaps, were the atrium and green houses that were favorite settings for romance in Victorian England. The lovers could get lost among the leaves of the exotic tropical plants and possibly mistake the hot, humid atmosphere for their own concealed passion.
The kairo
The Japanese have notoriously unheatable houses. They have traditionally preferred to design their houses to be cool and airy in summer and then to get by in the winter with localized ways to heat the body. Smallest of all means is the kairo, a little case carried around in pockets or between layers of clothes that contains a warm charcoal ember.
The ritualized use of a place
The association of comfort with people and place are reinforced by the ritualized use of a place. Using a place at a set time and in a specific manner creates a constancy as dependable as the place itself. It establishes, in time and behavior, a definition of place as strong as any architectural spatial definition, such as an aedicula, might be. Ritualized use can do more than reinforce the affection for a place. Through ritual, a place becomes an essential element in the customs of a people.
Functionalism can be a kind of religion
We are not now inclined to regard modern heating and cooling systems as representative of a spiritual realm. The physical principles involved in their operation are thoroughly understood; there is no mystery about them. They are simply functional, designed according to straightforward engineering practice to serve their intended function as efficiently and conveniently as possible.
And yet functionalism itself can be a kind of religion.
...From the fifties and sixties we have inherited numerous heating and cooling systems created within an ethos of universal convenience. Machines to maintain our thermal comfort were conceived of as mechanical servants, providing for our every need while, like an English butler, remaining as unobtrusive as possible.
Protected, yet tuned in
Karen Terry's house in Sante Fe, designed by architect David Wright, is perhaps one of the most compelling passive designs.
Stepping down its hillside site in four tiers, it nestles low into the ground. Thick adobe sidewalls create a strong sense of shelter and its banks of windows look resolutely to the sun. The image is very much of a house attuned to sun and earth.
Rather than providing the convenience of a constant indoor temperature regulated by a thermostat, a passively solar-heated house may go through an air temperature flux as great as 20ºF per day. People learn to live with this flux.
Living in a solar house is a whole new awareness, another dimension. I have the comfort of a house with the serenity of being outdoors—protected, yet tuned in.
Blessed by the four elements
The Indian stone temple also included, in its architectural form, the means for being blessed by the four elements—earth, wind, water, fire.
- Before entering the temple gates, one removed one's shoes to touch and be blessed by the earth.
- Then upon passing through the temple gateway, one is blessed by the air with a gust of wind.
- A blessing by water is obtained by bathing in the temple tank, or at least descending its steps to touch the water.
- Finally, on entering the cool interior of the sanctuary, the worshipper is given a mark on the forehead with ashes taken from a sacred flame by an attendant priest. Even this blessing by fire has a slight cooling sensation to it.
Perhaps it is only coincidental that each of these four blessings is associated with a cooling sensation; and yet, the use of forms and materials that inevitably create coolness is quite remarkable.
Each ruler commissioned his own garden
The Mughuls of India developed a tradition where each ruler commissioned his own garden. Then, "At the owner's death the pavilion, generally placed in the center of the site, became the mausoleum, and the whole complex passed into the care of holy men."
The ancient fire spirit who lived in the hearth
The garden is as central to the concept of an Islamic home as the hearth is to the European home. It is interesting, then, that the hearth-fire in old traditions has a similar association with the life of the inhabitants of the house.
Commonly, the fire of the hearth was not allowed to go out. It was carefully covered with ashes each night at curfew so that a few selected embers would survive until morning. (In fact, the word "curfew" originated from the French word for cover-the-fire—couvre-feu.) Raglan comments that "the alarm and horror felt if the hearth-fire went out are out of all proportion to the inconvenience caused" by the need to relight it.
The housewarming ceremony
The connection between the life of the fire and the life of the inhabitant is also reflected in the custom of the housewarming ceremony. In contemporary America a housewarming party is given when a family moved into a new house. Perhaps all of the friends and their good wishes are thought to warm the house metaphorically. In traditional cultures, however, the warming is quite literal, for it involves the bringing in, or the first kindling, of the hearth fire, which then creates the proper spirit and sanctity to transform the house into a home.
Fire, the animating spirit
We can easily imagine from our own experience why fire might be used as a symbol of the life of a house and the family that lives there. The fire was certainly the most lifelike element of the house: it consumed food and left behind waste; it could grow and move seemingly by its own will; and it could exhaust itself and die. And most important it was warm, one of the most fundamental qualities that we associate with our own lives. When the fire dies, its remains become cold, just as the body becomes cold when a person dies. Drawing a parallel to the concept of the soul that animates the physical body of the person, the fire, then, is the animating spirit for the body of the house.
