We're excited to launch Stop New Assignment, a new decision type for experiments in Statsig. This feature allows you to halt new user enrollments in an experiment while continuing to analyze the results for previously exposed users.
Example Use-case
Stop New Assignment offers flexibility in various scenarios. For instance, consider an e-commerce company running an experiment to measure the impact of discounts on repeat purchases. With a limited budget, you may need to cap the number of discount offers. However, measuring long-term effects on repeat purchases requires ongoing analysis for an extended period. Stop New Assignment addresses this challenge by allowing you to stop user enrollment once you've reached your budget limit while maintaining result analysis to assess the impact on repeat purchases.
Implementation in Statsig
To implement Stop New Assignment, simply select it from the Make Decision dropdown in your experiment interface. Note: this feature requires Persistent Assignment to be configured.
