Discover

Competitive research revealed how competitors present pricing breakdowns, manage promotions, and handle billing estimates, allowing the identification of gaps in clarity, offer visibility, and the overall flow of information during checkout.

Ideate

During ideation, opportunities to simplify the billing structure, improve the grouping of charges, and use clearer, customer-friendly terminology were discovered to reduce confusion and ensure a more intuitive checkout experience.

Protoype

Prototyping and testing focused on building interactive prototypes for different customer journeys, including new customers with or without trade-ins, existing customers upgrading their devices or adding a line, and BYOD (Bring Your Own Device) users. The new add-ons menu was tested for usability and efficiency, featuring an expanded view for clearer selections, a carousel for quick browsing, and applied add-ons displayed as chiclets for real-time visibility. Usability testing validated the effectiveness of these enhancements, ensuring that users could make decisions more easily and efficiently.

Refinement

Implement

Implementation and optimization involved close collaboration with engineers to refine interactions, particularly around dynamic pricing updates and real-time cart adjustments. Post-launch data was analyzed to track improvements in add-ons adoption, checkout completion rates, and promo utilization. Heatmaps, A/B testing, and customer feedback informed further optimizations, ensuring a continuously refined and user-centered experience.

The final version streamlined the user experience, integrating key insights to improve understanding of pricing and billing details. The recommendation was then sent to the VP of Shop and Purchase for review and approval.
