ONE Store is Korea's leading app marketplace.

I was engaged in preparing the ONE Store Admin app for new market entry.

Comprehensive UX and competitive analysis was conducted comparing features with Google Play Console and App Store Connect.

Challenge

The existing admin interface for setting up promotional campaigns (rewards, coupons, in-app purchase bonuses) had significant usability issues:

  1. Campaign setup took 1-2 hours per promotion

  2. New administrators required several days of training

  3. Complex documentation was often outdated

  4. High error rate in campaign creation due to confusing workflow

The core problem was an intricate event architecture with nested components and complex attributes, causing systemic errors, inefficient navigation, and ad-hoc configuration workarounds.

Design challenge: Develop a solution that improves usability and navigation without completely rebuilding the system from scratch.

Solutions Implemented

  1. Restructured information architecture

  2. Eliminated edge cases that forced admins to restart campaign creation

  3. Removed redundant attributes that caused field conflicts

  4. Simplified workflow by eliminating recursive patterns

  5. Redesigned navigation for intuitive use

Outcome

  • Campaign setup reduced to minutes

  • Intuitive interface requiring minimal training

  • Streamlined workflow with error prevention

  • Self-explanatory navigation system
