Invention requires failure

–Albert Einstein
“Anyone who has never made a mistake has never tried
anything new.”

“Failure is success training.”
-Kevin Smith

Creating a fail-safe environment

Fail Smart

–Mikael Krantz
"we want to be an internal combustion engine, not a
fuel-air bomb. Many small controlled explosions
propelling us in a generally ok direction, not a huge blast
leveling half the city”
Minimize the blast radius

Find the fastest, cheapest path to learning.
Fail fast

The lesson of Clippy

– Thomas J. Watson
“If you want to increase your success rate, double your
failure rate.”

punish not learning from failure
Do not punish failure

Each failure tells you something about
• your process
• your team
• your perception of your customers
• your understanding of your product
• yourself
Extract the lessons from failure

Do project retrospectives with the intent to not only figure
out what happened on the project, but with the intent to
make future projects better.
Extract the lessons from failure

Create a shared repository of the lessons learned.
Catalog the lessons

Failures hidden or forgotten are failures that will be
repeated.
Catalog the lessons

– Bob Sutton
“The most creative people — and companies — don’t
have lower failure rates, they fail faster and cheaper, and
perhaps learn more from their setbacks, than their
competitors.”

The lesson of Spotify Now

Expect failure all the time

http://techblog.netflix.com/2010/12/5-lessons-weve-learned-using-aws.html

Smaller/Micro Services, loosely connected, mean smaller
failures
Small systems have small failures

Roll new things out over time, watch how your users react,
watch how your systems scale, watch your customer service
queues, watch your analytics, watch your crash logs.
Take your time

Putting this into practice @ Avvo

Creating a supportive culture

Moving from planning around commitments to planning
around priorities

Talk about when things don’t go well with an eye to future
improvement rather than blame

Do retrospectives
In your retrospectives, think beyond the current project to
future projects.
The goal: continuous improvement.

Monoliths are natural when a small team (or a startup) are
building a product.
Building lots of small services means building infrastructure
to support them.
The trick is knowing when it is time to make the transition.
Fail-safe infrastructure

time more intelligently”
