When Scaling, the context is different
CONTEXT
Single team Agile at Scale
7-9 > 100sTeam Size
Co-located GlobalGographic Distribution
Single Division Multi-departmentOrganizational Distribution
Less or none Life Crit icalCompliance
Straightforward ComplexDomain Complexity
Straightforward Multi-platform / complexTechnical Complexity
Less or none Upstream / DownstreamIntegration needs
Homogenous Heterogenous mixEnvironment complexity
Slide 3
Case with multiple
teams
CONTEXT
▸ Can velocity scale
linearly? i.e. to achieve
more velocity can we add
more teams?
▸ Dependencies will
dampen the velocity
Sl ide adapted f rom Nexus presentat ion in Scrum.org

Reification – making a
concrete, worthwhile
integrated product
consumes additional
overhead
▸ Continuous Integration
▸ Automation

So Scrum is indeed fractal at Scale!
With principles of Scrum intact
Principles Scale fractally
Underlying Principles of Transperancy,
Visibility, Frequent Inspection and

Practices do, in Nexus
Layered Sprint ceremonies help it
achieve

CLOSURE
A fractal is a natural phenomena and a
mathematical set. What they have in common is a
repeating pattern that displays at every scale.
