User story & summary:

As the Growth team, we want to ensure that the SUL3 (Single Unified Login) release does not negatively affect login or account creation, as these are critical steps in the editor funnel and user workflow.

Any disruption in account creation or login could hinder new user activation and editor retention, which are key metrics for Growth team objectives.

Task scope:

This task focuses on defining the analytics approach to measure the impact of changes to the login and signup flows resulting from the SUL3 release T348388: SUL3: Use a dedicated domain for login and account creation .

Specifically, it involves evaluating existing instrumentation, reviewing rollout plans, and recommending further tracking or engineering enhancements to accurately monitor user impact.

Note: The impact on users may depend on UX choices made in T364941: Decide on the login flow in MediaWiki under SUL3.

Acceptance Criteria:

• Review the current instrumentation related to login and account creation flows (e.g., success rates, error tracking).
• Summarize findings and insights in this task, highlighting any potential gaps.
• Evaluate the rollout plan for SUL3; is there an opportunity for A/B testing?
• Recommend additional instrumentation or engineering efforts (if needed) to ensure comprehensive tracking of user impact post-release.
