How might we enable data-informed decision making
at scale in an organization with > 10k employees?

Forces of gravity in
a big organization:
• Fragmented tracking
• Data silos
• Unclear data quality
• Time-consuming access
to data and tooling
• Missing analytical rigour

and multiplier level

What are our learnings
from the last months?
Example experimentation
13
Spark a fire:
Teams intrinsically get
into the flow of iterating
optimization cycles
when seeing the first
encouraging results
Picture
14
Have the right balance
between small + big ideas:
Don’t only do frontend
testing, think about bigger
experimentation
use cases that involve
backend testing
Picture
15
Think beyond data:
Use qualitative research to
get at the why. The value
is in the insights behind
data
Picture
16
Set expectations:
• Success looks like:
Increasing number of tests
and teams
• Only a part of tests with
significant results
• Nonsignificant results
don’t mean no learning
• Avoiding downlift easier
than generating uplift
