Assign Experiment Control Groups strategy
At my current project we want to implement control groups for certain actions.
Eg: Action 1 only 90% of the customers will receive if eligible and Action 2 only 10% of the customers will receive if eligible. The business wants to implement this via Control Group in order to analyse the data in IH and see if the Action 2 get a better response than action 1. We are also planning an upgrade to Pega 8.8 and I saw on the documentation that CDH generates a strategy called "Assign Experiment Control Groups". Is there any configuration in NBA Designer in the Pega 8.8 that will help us to assign different control groups at the action level or the approach is to customize one of the extension point strategies? Any recommendation on control groups will be greatly appreciated.
