#### Background
This task is intended to capture what data wiring is needed to answer if this feature met its goals.
##### Measurement Goals
**Validation**
//These will be measured via an A/B test //
- KR 1.1 8% increase in users initiating Search from article view
- Control group: unique users in A who have initiated at least one search from article view/unique users in A who have had article views
- Variant group: unique users in B who have initiated at least one search from article view/unique users in B who have had article views
- KR 1.2 1% higher app retention rate for users that had the more prominent article search (using [[ https://meta.wikimedia.org/wiki/Research_and_Decision_Science/Data_glossary/Retention_Rate#Retention_rate_of_one_cohort | 2-week retention ]])
- Control cohort: of the unique users in A who engaged with the control search icon, what % were retained to the app?
- Variant cohort: of the unique users in B who engaged with the variant search bar, what % were retained to the app?
- KR 1.3 5% increase in average pageviews/unique user for those who engaged new article search bar
- Control group: average pageviews/unique user for users in group A who initiated at least one search from article view
- Variant group: average pageviews/unique user for users in group B who initiated at least one search from article view
**Guardrails**
- GR 2.1 No more than 10 negative user complaints about changes to the Navigation that can’t be addressed
- GR 2.2 No more than 5% increase in app uninstalls
- GR 2.3 No more than a 10% increase in app crashes
**Curiosities**
- CR 3.1 Do we see a difference in the KRs for logged in users vs logged out users
- CR 3.2 Did account creations increase as a result of the Profile menu being accessible from all screens?
- CR 3.3 Did usage of History change due to its move into Search?
- CR 3.4 Do users prefer a different location for the article view search?
- CR 3.5 What was the feature retention rate for article search for both A & B? (Recalculate 1.2 but using return to engage with article search as definition of retention, not return to overall app)
##### Link to Finalized Designs
- Navigation Part 2 designs: https://www.figma.com/design/utNpL8yrjrDkDmlO9qS4T5/iOS-Navigation-(Robin)?node-id=679-745&p=f&t=YUiSsRUkT16A9s2k-0
- Search prominence A/B test will look like this:
