Leanplum will never automatically decide a winning variant. We feel strongly that you know your business best and should ultimately decide the winning variant. Our goal is to empower you with all of the information about a given test so that you can make the most informed decision possible.
Once you have decided the winning variant, you can finish your test and roll out the winning version. From the A/B Test Analytics page, navigate back to your test’s setup page.
Click on I’m Finished in the top right hand corner of the page. If you want to remain with the control group, simply select Control and click Finish. Alternatively, if you wish to roll out one of the variants and you have defined a target, you must first decide whether to roll out the winning version only to the users who were targeted within the test, or all users. Once you have decided which users you would like to affect the change for simply click Finish.
Your final changes will be copied into the variables tab as an override segment and the change will be live for all users matching the targeting criteria the next time they open the app.
Note that once a test has been finished it cannot be reactivated. You will have to create a new test.
