What is “Simplicity”?

What is it good for?

How to create it?

…


Three perspectives:

● the manager’s

● the engineer’s

● the user’s


Simple doesn’t mean minimal.


Simplicity isn’t something you

can stick on top of a user

interface .



What is this for?


The experience I want the users

to have


First, understand the users’

world, then figure out how your

design fits in .


Get out of your office


The best place to watch users is

in their

natural environment


What to look for:

● Offices

● Homes

● Outdoor


At home, at work, and outdoors,

you must design for constant

interruptions .


Three types of user:

● Experts

● Willing adopters

● Mainstreamers


Sometimes, it’s best to ignore

the expert customers.

Experts often want features that

would horrify mainstreamers .


If you want simplicity, if you want

to be seen as an innovator, then

it’s the mainstream customers

you should be aiming at.


Mass appeal comes from

focusing on the mainstream .


What mainstreamers want


Mainstreamers are interested in

getting the job done now; experts

are interested in customizing

their settings first.


Mainstreamers value ease of

control; experts value precision

of control.


Mainstreamers want reliable

results; experts want perfect

results.


Mainstreamers are afraid of breaking

something; experts want to take

things apart to see how they work.


Mainstreamers want a good

match; experts want an exact

match.


Mainstreamers want examples

and stories; experts want

principles.


Simple user experiences need to

work for a novice, or a

mainstreamer who’s under

pressure.


Mainstreamers don’t want to

build it from scratch .


People are driven by an

emotional need


Make user feel confident that

they’d be able to put tasks away

and find them again later.


Simplicity is about feeling control


Simple experiences make users

confident that they’re making

good choices.


Simple experiences reassure

users that the product will

respond in a predictable way.


describe the beginning to the end of their experience,

remembering that the user’s actions is most important


Turn problem into a vision. Tell

the story.


Describe what you want in the

simplest possible terms .


World, character, plot:● A believable world (the “where” and “when” of our story)

● Credible characters (the “who” and “why”)

● A coherent plot (the “what” and “how”)


Extreme usabilityUsability aims for...

● a specific group of people can use it● easy to use● responds quickly● understood quickly● works reliably● straightforward error messages● complete information● works in a user test

Simplicity aims for...

● anyone can use it● effortless to use● responds instantly● understood at a glance● works always● error-free● just enough information● works in a chaotic environment


Review your story and ask: What

things have the most impact on your

users’ behavior?


Check the facts about the users, their

problems and the world they live in.

Prioritize things that have the most

impact on your users’ behavior.


Prioritize points to act on: where can

you have the most impact? What can

you change easily?


Test your insights


The most obvious way to simplify is to

remove what’s unnecessary


Do not remove features only because

they are difficult to build.


Improve the core experience


Customers chose basic improvements

over value-added extras .


Get rid of poorly implemented features


The question is never, “Why should we

get rid of it?” It is always, “Why should

we keep it?”


Stop guessing “what if...?” and go find

out what is.


Features often involve trade-offs that

customers aren’t always aware of.


Don’t be afraid to ignore requests to add

more to your product.


When a small change leads to complex

processes, it’s time to step back and

find another solution .


In the long run, adding features is a

losing strategy .


Identify the users’ goals and set them in

order of priority.


Focus on solutions that completely meet

users’ high-priority goals.


Identify things that are common sources

of anxiety or stress and prioritize

features that alleviate that stress

effortlessly.


Identify the “good enough” controls that

satisfy mainstream users’ needs and the

“precision” controls for experts.

Set aside the “precision” controls.


Don’t judge your product by the number

of features. Instead, consider if it meets

users’ high- priority goals.


People have a limited capacity to

process information, learn procedures,

and remember details.


Removing options, content, and distractions lightens the load on users so they can

focus.


Removing visual distractions helps them

process what they’re seeing faster and

more reliably.


It’s the details that make all the

difference.


Choice can easily overwhelm users.


People having limited choice are more

satisfied with their selection than those

who’d been given more options.


Irritating distractions can turn simple

tasks into a chore.


Designing simple experiences, your job

is to remove distractions and let the user

focus.


Mainstream users don’t like the burden

of setting options and preferences .


Whenever a user has to correct an

error, it breaks his concentration and

makes the experience feel more

complex.


Removing sources of errors is an

important way to simplify an experience.


Remove visual clutter so people process

less information and concentrate on

what’s important.


Users don’t read every word. They skim

over pages, picking out the odd keyword

or sentence.


Simplify with a shared vision, a focus on

the mainstream user, and a thoroughly

researched design.


Organizing is often the quickest way to

make things simpler .


Break items down into groups of “seven

plus or minus two.” This corresponds to

the number of items your brain can hold

in short-term memory.


Understand users’ behavior: what they

want to do and in what order they want

to do it.


To organize a group of items that are

equivalent choose clear categories with

labels that make sense to your

audience.


Organizing by a quality results in problems since users make different

choices depending on their point of view.


Hiding anything means putting a barrier

between the user and the feature.


Profile settings

that change infrequently are good

choices to hide .


Invite to explore. Small cues can hint at

hidden features . For example using

label that will only appeal to a certain

group


Where you place a label is more

important than how big it is.


Locus of attention

Area of the screen that the user is

concentrating on.


The strategies: remove, organize, and

hide fit together neatly: remove what

you don’t need, organize what you do,

hide what you can.


The final strategy, displace, is about

rethinking the interface entirely.


Mobile devices to record what users

see, hear and where they go .


Entering and reading large amounts of

text is uncomfortable .


Mobile devices are used when walking,

standing, sitting, lying. Outside, inside,

with sunshine , rain, wind and snowfall.


Be aware of data transmission and

signal strength on mobile.


The user is directing, the computer guiding, the experience feels simpler .


Let experts and mainstreamers set their own goals. Based on their experience they know how much effort it will take.


Should a task be automated or

controlled by the user?


Create a simple user experience shifting

complexity into the right place, so that

each moment feels simple.


Simplicity often depends on details.


Missing details can have a catastrophic

effect or cause irritation that builds over

time.


Simplicity happens

in the user’s head


Making software usable means not

exceeding your users’ capacity.
