Should Optimizely prioritize adding more advanced statistical models to its A/B testing platform or focus on simplifying the user interface for better adoption among non-technical users?

Introduction

The trade-off question at hand is whether Optimizely should prioritize adding more advanced statistical models to its A/B testing platform or focus on simplifying the user interface for better adoption among non-technical users. This scenario involves balancing technical sophistication with user accessibility, a common challenge in product development. I'll analyze this trade-off by examining the product context, potential impacts, and key metrics, then design an experiment to inform our decision.
