What happens if
your brakes
don't work?

Cars have brakes
so you can
drive faster

over under
capacity capacity

under
capacity
◦For a while increasing
the density increases
the flow.
◦Increasing the flow
causes the density to
reduce.
◦ Thus you have a
stabilizing feedback loop
helping to increase the
flow.

◦As you continue to
increase the density
you reach the top of the
ﬂow-curve.

over
capacity
◦As the density
increases the flow
decreases.
◦Decreasing the flow
causes the density to
further increase.
◦Thus you have a
different destabilizing
feedback loop helping
to decrease the flow.

The total absence of
meaningful practice... is
probably the predominant
factor that keeps... teams
from being effective learning
units

Deliberate
Software
Team
Practice

Effort is one of the
things that gives
meaning to life. Effort
means you care about
something

It's not the event that
counts, it's your
reaction to the event

"There's nothing
on the internet
about X"

"I can't ﬁnd
anything about X
on the internet"

"Dad. Will you
help me with my
homework?"

The ethics of the
Havamal are above
all rooted in the
belief in the value of
the individual

A log's flame
leaps to another
fire kindles fire.
A man listens
thus he learns

Boyd’s Law
The speed of an
iteration trumps the
quality of an iteration

Jeff Atwood

When in doubt,
iterate faster.

Jeff Atwood

the ability to quickly
.
slow down is as
important as the
ability to quickly
speed up

Boyd despised
optimization

.Boyd worked daily
to remove things

Again and again
they practised

Boyd liked
ambiguity

Improvement
is easier than
perfection
Chinese saying

As consultants, we've
found that the
quickest and surest
way to classify
organizations into
similar patterns is by
the way people think
and communicate

No other observation
skill may be more
important to software
engineering than
precision listening

When an actor comes to me...
If he says
"what's my motivation?"
I say...

Do More
Deliberate Practice
You do deliberate practice
to master the task not to
complete the task.

Binary Tweets
Readability is one optimization
that can never be too premature

Never listen to anyone who has
never made a mistake

Virtually all truth
is paradoxical

It is not the strongest
of the species that
survive, nor the most
intelligent, but the
ones most responsive
to change

commonly mis-attributed to
Charles Darwin

The better adapted
you are, the less
adaptable you tend
to be

Sir Ronald Fisher

If people knew how
hard I worked to get my
mastery, it wouldn’t
seem so wonderful after
all

biggest change
you'd like to see
in the software

“Slowing down in
order to do
things right”

“What would it
take to make
this happen?”

“Hell would have
to freeze”

“Things take the time
they take, not the time
you hope they will take.
Pushing for half time
produces half baked”

Every effect has a
single cause...

Unary Tweets

The real problem is...

The problem with
motivational speakers is...

Every effect has a
single cause...
...and we can tell
which is which.

The more error
prone a module is
the later it will be.

The later a module
is the more error
prone it will be.

Systems inherently
resist change

.
...more usable
energy goes into a
system than
comes out,
because there is
always
unavailable
energy called
entropy

As teenagers,
band X worked in
Hamburg, ... doing
8 hour sets,
7 days a week,
for months on end

Don't be afraid to
cultivate your
unconscious

The development of
consciousness is thus,
among other things, a
process of the conscious
mind opening itself to the
unconscious in order to

Make the Invisible
More Visible
You manage things better
when you can see them
and see them constantly
changing

The absence of fear is
not courage; the absence
of fear is some kind of
brain damage. Courage is
the capacity to go ahead
in spite of fear

The meaning of a
communication is
the behaviour
that results

The art of maximizing
the amount of work not
done.

Just calling it
“feedback” doesn’t mean
that it has actually
fed back

It hasn’t fed back until the
system changes course

Courage
Communication
Feedback
Simplicity

... tell us how
software
development
should feel.

Bureaucrat
One who has the
power to say “no”,
but none to say “yes”

Bureaucracy
Each thing in control,
but the whole thing out of
control

Bureaucracy
Can be measured by how much
people don't know why their
doing what their doing

Wisdom is not something
you learn.
Wisdom is something
which will come out of
your mindfulness.

Right practice,
Right attitude,
Right understanding
