Why diversity?
"When Fortune-500 companies were
ranked by the number of women
directors on their boards, those in the
highest quartile in 2009 reported a
42% greater return on sales and a 53%
higher return on equity than the rest."
OpenStack: Deliberate Diversity
•  First open source community to recognize
non-technical contributions
•  Strong commitment to maintain *one*
community, through a single summit
•  Regional, commercial, cultural, size, age,
gender, language… and mindset.
"...diversity can in theory be very beneficial to
team performance, particularly when
innovation is the goal. However, to get the
benefits of diversity, the team members must
work well together…
…diversity, absent explicit conditions to
engender collaboration, actually limits the
exchange of ideas among team members."
Cohesion
Social Cohesion
Reflects the degree to which members of a
team like each other and enjoy each other's
company.
Task Cohesion:
The degree to which members of a group
work together to achieve common goals.
Winning comes from… ?
Social Cohesion:
•  Reflects the degree
to which members
of a team like each
other and enjoy
each other's
company.

Task Cohesion:
•  The degree to
which members of
a group work
together to
achieve common
goals.
Why now?

(Some thoughts on the collapse of the Mongol Empire)
Drinking is no longer enough.
Intermission:
Chickens and Pigs…
“You’re involved… but I’m
committed.”
OpenStack:
Bacon-wrapped Chicken Dinner.
Common Barriers to Group Cohesion
• 
• 
• 
• 
• 
• 

Clash of personalities in the group
Conflict of task or social roles among members 
Breakdown in communication 
One or more members struggling for power
Frequent turnover of group members
Disagreement on group goals and objectives
Solution: Understanding each other
The “Hoodie”
•  Maker Time
•  Asynchronous
communication
•  Inside-out view
The “Blazer”
•  Manager Time
•  Synchronous
communication
•  Outside-in view
Working together
The difference between a tolerable
programmer and a great programmer is not
how many programming languages they
know, and it's not whether they prefer
Python or Java. It's whether they can
communicate their ideas.
- Joel Spolsky
The lower the rank of managers, the more 
they know about fewer things. The higher 
the rank of managers, the less they know 
about many things.
- Russell Ackoff
But there’s one more thing…
To produce the ubiquitous open
source cloud computing
platform.
“There is no them;
there's only us.”
- Bill Clinton
