The purpose of
“scaling is to get
more done in a
given timeframe.
But what do you
want more...
Output or Value?
Why Scale?
3
• Because we need to go faster?
• Because we have a lot of people?
• Why else?

• Identify and resolve or minimize
dependencies:
• Ongoing & persistent
• In all dimensions
• Prior to work occurring
• Reactive to ensure that
undetected dependencies
aren’t corrupting outcomes:
• Frequent integration
• Acceptance testing
• Continual build and delivery
• Minimize technical debt
Essence of Scaling
ANTICIPATION* REIFICATION**
** The process or result of reifying.
Making something real, bringing something into
being, or making something concrete.
* The act of preparing for something.
A prior action that takes into account or forestalls a
later action.

• Scale for value not for output.
• Nexus extends Scrum by creating a network among the teams.
• Be rigorous about removing dependencies and creating an
Integrated Increment at least every Sprint.
• Integration is also about the connection between people.
• Scrum provides a great framework from which to scale with Nexus.
• And remember, without first implementing the foundational Scrum
concepts, any scaling will be painful and will actually reduce
productivity.
