Leveling up: Instrumentation
Closed, ResolvedPublic


User story:

  • As the Growth team, I want to understand how Leveling up (part of the Positive Reinforcement project) has changed newcomer behavior, because I want to see if this work was effective and I want to know if any improvements should be made.
  • As a Wikimedian, I want to make sure new Growth features are working well for newcomers, because then I'll be more accepting of the changes when they are rolled out on my wiki.

The Levelling up instrumentation section in the measurement specification is now complete and ready for review and/or implementation. I'll be in charge of updating the measurement specification based on any changes that come out of the development process.

I can claim this, but the patches for instrumentation are in subtasks. So I'll move it to "In progress" for now, and when the subtasks are in QA, I'll move this to QA as well.
