January 2025 focused on delivering a reusable CompletionIndicator UI and strengthening test quality for Measure Groups. Key outcomes include a reusable CompletionIndicator component with visual cues (checkmark or error) integrated into the Measure Groups UI across Populations, Stratifications, and Reporting for both QDM and QICore, improving feedback consistency and user experience. Additionally, the Measure Groups test suite was hardened to reduce flakiness and regressions by removing test-only modifiers, correcting the improvement notation handling, and cleaning up test code. These efforts improved user feedback, reduced risk of UI regressions, and strengthened release quality and overall product confidence.
