Video and slides synchronized, mp3 and slide download available at URL https://bit.ly/2SXXXiD. Katharina Probst talks about what it means to act like an owner and why teams need ownership to be high-performing. When team members, regardless of whether they have a formal leadership role or not, act like owners, magical things can happen. She shares ideas that we can apply to our own work, and talks about how to recognize when we don’t live up to our own expectations of acting like an owner. Filmed at qconsf.com. Katharina Probst is a Senior Engineering Leader, Kubernetes & SaaS at Google. Before this, she was leading engineering teams at Netflix, being responsible for the Netflix API, which helps bring Netflix streaming to millions of people around the world. Prior to joining Netflix, she was in the cloud computing team at Google, where she saw cloud computing from the provider side.

11. ONE SERVICE’S EXPECTATIONS FROM ANOTHER
Clean APIs
Articulate what you
can do and what you
can’t do.
It’s your
responsibility to get
what you need from
your downstream
systems.
Status codes
Your responses
should give me clear
indication of what to
do next.
Fail fast
I don’t want you to
fail. But if you do, I
want you to let me
know instead of
timing out.

12. HOW TO AVOID FAILURE MODES
No SPOF
◦ There should not
be only one
server/zone/
region who can
handle this type of
request.
Don’t always say
yes
◦ Every request
that comes in
seems important.
◦ If everything’s a
P0, nothing is.
Communicate
◦ Everybody should
know my system’s
/ their request’s
status.
10

13. PROACTIVE WORK IN SYSTEMS
Thinking ahead
◦ How much traffic will my
system need to handle in
1 or 2 years?
◦ What do I need to do to
set myself up for
success?
More thinking ahead can
mean less reactive work
◦ Precomputation
◦ Garbage collection /
compaction

18. ONE PERSON’S EXPECTATIONS FROM ANOTHER
Clean APIs
Articulate what I can
do and what I can’t
do.
It’s my responsibility
to get what I need
from my teammates
or downstream
teams.
Status codes
My responses should
give you clear
indication of what to
do next.
Fail fast
You don’t want me to
fail. But if I do, you
want me to let you
know quickly instead
of timing out.

42. WHAT I LEARNED
Human systems ~
Distributed
computer systems
◦ Clear expectations
help.
◦ Both will fail
(eventually).
Do less, but do it
well
◦ Pick and choose,
but then aim for
a high SLO.
◦ Say no more
often (but
explain why).
Communication is
key
◦ Let others know
what you can and
cannot do (clean
APIs).
◦ Minimize timeouts.
40

43. WHAT I LEARNED - (SELF-)COMPASSION
I can’t do everything
Don’t spread yourself too
thin.
I don’t expect others to do
everything
Understand that others are
under the same pressures.

This means that you can:
● Resize them without
losing quality.
● Change line color,
width and style.
Isn’t that nice? :)
Examples:

And of course it resizes without losing quality and you can change
the color.
