Not all work is created equal


Book writing ≠ Work

• You are the boss (customer)

• There is no one telling you what to do

• You decide when it’s ‘good enough’

• You decide when it is done

• It ceases to be work - and becomes something else


The work becomes art.Hint #1



Abandon your idea as soon as a better one comes along ‘pivot’


Makes sense right?

Just pivot!

Got a bad idea?


Just one problem...

What if you don’t care what others think?

What if you don’t wan’t to pivot.


My good friend

Last thing this world needs is another book

on agile.


“We think the Mac will sell zillions, but we didn’t build the Mac for anybody else.

We built it for ourselves. We were the group of people who were going to

judge whether it was great or not. We weren’t going to go out and do market research.

We just wanted to build the best thing we could build.” Steve Jobs


Speculative & Personal


Speculative ideas


Personal ideas


It’s personal.Hint #2


Purpose


The purpose of a company

“If anything imaginable is possible, If there are no constraints whatever, what would be the nature of an ideal organization to...”

Dee Hock, Founder VISABirth of the Chaordic Age


• Autonomy

• Master

• Purpose

There is a class of work that defies ‘management’



There’s a strong purpose.

Hint #3


The work becomes artIt’s highly personal, andThere’s a strong sense of purpose

So when...

Formal methods


Unit tests = Quality


• Unit tests

• TDD

• Continuous Integration

• Refactoring

My first iOS gig


• Unit tests

• TDD


• Refactoring

It worked!

The hypocrite


•Unit tests

• TDD


• Refactoring

Not doing this one really bugged me

The rational explanation

• Smaller screen size

• One language

• No legacy

• Very visual

But that still didn’t explain the reputation for quality.


#1 Reason why I believe iOS developersbuild quality products without extensive

suites of unit tests...


They care.


Out caring the competition

• Care about the art

• Care about the experience

• Care about the words

• Human interface guidelines

• They curate out bad apps

• They make is easy to care - it’s expected


The iOSHuman Interface Guidelines


Care about art


Care about experience

• Focus on the primary task.

• Elevate content people care about.

• Make usage easy and obvious.

• Minimize effort required for user input.

• Be succinct

• Consider adding physicality and realism

• Delight people with stunning graphics


Care about words

• Write text that succinctly describes the situation and explains what people can do about it.

• Avoid single-word titles that don’t provide useful information.

• Title-style capitalization

• Sentence-style capitalization


They just care very deeply about the ‘quality’

of what they build.


What does this have to do with unit tests?

(absolutely nothing)

98%

Everything else Unit tests

How I see the world now


Note: I am not saying

• Unit tests are not important.

• Unit tests don’t contribute to quality.

• iOS developers don’t need to unit test.


What I am saying:

• There is a lot more to quality than unit tests.

• There is a lot I can learn from this community in terms of quality.

• I still have a lot to learn in terms of building a quality product and experience.

• Don’t judge (the Apple community)


Want better UX?Want higher quality?

Want better customer service?

Find people who care.(the rest will take care of itself)


The Point

• Whether you agree/disagree with these assertions I am making doesn’t matter.

• What matters is...


Your cheese will move• Never assume you’ve got it all figured out.

• If it makes you uncomfortable that’s good!

• It shows you care.




Thank you
