Card Page Full Redesign Mixed Methods Research Program

December 2025 – July 2026

Overview

Over a seven-month period, I led and supported 11 mixed-method UX research studies to redesign Birbank's Card Page. The goal was to understand user needs, validate design decisions, prioritize features, and reduce friction in one of the application's most frequently used sections.

The research combined qualitative and quantitative methods, allowing product and design teams to make evidence-based decisions instead of relying on assumptions.

My Role

Planned research roadmap together with Product Designer and Product Owner
Designed research methodologies
Conducted moderated usability testing
Conducted card sorting
Performed quantitative analysis (clickstream, call center and feature usage data)
Identified root causes behind usability issues
Presented findings and recommendations to stakeholders
Worked closely with Product Design and Product teams throughout the redesign process

Research Timeline

Month	Discovery	Validation	Quantitative	Design
Dec	3DS Notifications Research
Jan				Cards Menu Initial Redesign Research
Feb		History & Banner Testing		History & Banner Testing
Apr			Feature Prioritization (MaxDiff, Clickstream, Call Data)
May	Security Root Cause Research	Card Sorting
Jun		Card Actions A/B Test Card Reissue Validation

History Button A/B Test | | jul | | Final full redesign usability and impression tezt | | |

Research	Goal	Outcome
Cards Menu First Redesign	Validate action list concepts	Hybrid navigation selected
Card Sorting	Organize Card Actions	Information architecture optimized
History Button Testing (2 iterations)	Compare 5 alternatives	Two strongest designs identified
Feature Prioritization (MaxDiff + Click + Call data)	Prioritize features	Four priority groups created
Security Root Cause Research	Understand 3DS issues	Awareness identified as key driver
Security A/B Test	Validate new entry points	Dual-entry approach recommended
Card Actions List A/B test (nested vs open-list card actions)	Test design and cognitive load	Hybrid model recommended as optimal design
Card Reissue Validation	Test wording and design	Improved comprehension
Final Card Page Redesign Tests	Validate end-to-end experience	Design improvements confirmed

Key Research Insights

1. Hybrid Action List performed better than fully open or fully collapsed navigation

Through usability testing, users consistently completed tasks faster and with less confusion using a hybrid interaction model. This approach became the foundation of the final Card Page navigation.
