Pivotal Labs
Mission is to transform the way the world builds
software
Disciplined form of Agile since late‘90s (iterations,

Honed processes over ~15 years and ~500 client
projects
Now a key component of Pivotal

What Matters: Apps. Data. Analytics.
Apps power business, and
those apps generate data
Analytic insights from that
data drive new app
functionality, which in-turn
drives new data
The faster you can move
around the cycle, the faster
you learn, innovate and pull
away from the competition

But, What is Agile?
Like going to the optometrist
At the end of the engagement, both you and your
optometrist know your prescription

What About in Software
We believe that software should be built:
– in short iterative feedback loops
– as a team sport
You have the right to get smarter over time
– Product definition is always in flux
Expectations for development teams are at all-time
high (not just in speed)

What Does Business Really Want?
Consistent rate of output
No surprises
Prefers “fast and predictable” over “sometimes
super-fast, sometimes mysteriously slow”
...all in the face of constantly changing product
definition
Every product owner wants predictability:

“GOOD”
Think of a “good” software team as one that
can continuously build whatever it’s asked,
over an indefinite time period
That’s very hard :)

How/Why Does Pairing Work?
How?
– Two keyboards, two mice, two monitors, two engineers
+ 1 keyboard
– Like two pilots in an airplane cockpit
– Exhausting for the first 3 weeks you try it
Why?
– Pair pressure
– Removes obstacles
– Limits distraction

Test-driven Development
Tests are written first(!)
Write code until the tests pas
You’re done, go write a new failing test
Best sleep you’ll ever have as a software engineer
Why does this work?
Is it really faster?

Continuous Integration
Visible build monitor
Instant regression
Fixing the build is the #1 priority
Integrate early and often
Product can test anytime and create milestones
markers without worry
