Optimizing Innovation: The A/B Testing Platform
Re-architecting a mission-critical internal tool to cut experiment setup time by 40%, enabling hundreds of teams to ship data-validated features daily.

Executive Summary
The Mission
Redesign the internal "Experimentation Hub" to make complex data science accessible to product teams.
Target
Designers, Product Managers, and Engineers across Booking.com.
Key Result
40% reduction in setup time; shift from 2-week lead times to self-service launches in days.
Governance
Implemented automated guardrails to prevent statistical errors in experiment design.
Behavioral Shift: Autonomy over Friction
Before (The Bottleneck)
- • Teams relied on data scientists for basic configuration.
- • UI was built for technical experts, excluding 60% of product teams.
- • Manual validation processes led to 15% "invalid" experiment setups.
After (The Empowerment)
- • Self-service wizards guided PMs through statistical setup.
- • Real-time data visualization enabled fast "go/no-go" decisions.
- • Experiment integrity improved by 25% via automated validation.
DesignOps: Democratizing Data
For an internal platform, documentation isn't enough. We built a support ecosystem to ensure every team felt confident running high-stakes tests.
In-App Education
Embedded contextual tooltips and guides explaining complex statistical terms (e.g., P-values) in layman's terms.
Setup Wizards
Modular workflows that broke down experiment creation into 4 logical steps, preventing cognitive overload.
Community Support
A central hub for sharing "Wins & Fails," turning the platform into a collaborative learning environment.
Strategic Assessment (SWOT)
Strengths
Drastic reduction in technical barrier to entry; high internal product team NPS.
Opportunities
Integrating AI to automatically suggest experiment variations based on historical success data.
Weaknesses
The platform's visual density remains high due to the necessity of showing large data sets.
Threats
Over-testing can lead to user fatigue if teams don't align on overlapping experiments.
