Description
This skill provides a structured approach to planning and implementing split tests, multivariate experiments, and growth playbooks. It helps growth engineers move from a raw hypothesis to a measured result by defining variant copy and calculating statistical significance.
By focusing on experiment velocity and the use of ICE scores, the skill transforms ad-hoc testing into a repeatable experimentation program for measuring performance across different versions of a product or campaign.
