We like data
Why get started with data?
- Make better decisions- Objective decision making- Measure what users do rather than what they say they do- Find problem areas in your product- Understand your traffic

We like experiments
Experiment data can uncover the importance of small changes
Product strategy = “Increase the KPI”

Quantitative data is not a substitute for qualitative insight
Defaulting to hotels• 20% increase
travellers booking flights and a hotel
• Negligible impact on flights metrics
“Please stop defaulting me to Hotels I’m here for
flights!!”
“I do find it quite annoying because
when I look for Skyscanner what I
want to search for is flights, not hotels.”
All data has assumptions
Non-airport city search
- Obvious problem
- Complex build- Small use case- Problem not seen
in our data
“Rubbish instrumentation implies experienced guess is better than data led...”
“Should we always ignore what the data
says, or just this once?”
