// SCENE 01

Context & business goal

Claro's Devices PLP had launched a new card model with strong performance. The Accessories PLP was still on an older layout with weak support for campaigns, strategic highlighting, and consistent brand patterns — creating friction in cross-category navigation and missed merchandising opportunities.

// SCENE 02

Solution overview

  • Mondrian 6 product cards — clearer hierarchy between image, title, price and actions; better scannability for dense catalogs.
  • Dynamic badge system — New, Launch, Last units, Offer — driven by existing catalog & campaign rules with no manual intervention.
  • Centralized badge priority rules to prevent overcrowding across squads and surfaces.
  • Badges wired into commercial filters so users can filter by campaign or product status.

// SCENE 03

Personas

  • Cold audience — retail-driven shoppers from media/CPC, comparing Claro to Magalu and Casas Bahia. High price/fraud sensitivity.
  • Warm audience — loyal customers from Minha Claro and direct marketing. Expect VIP treatment and personalized recognition.

// SCENE 04

Results & impact

  • +10% CTR · +5% conversion · +20% badge-filter interaction · <1% bug rate.
  • Unified visual language across Devices and Accessories PLPs.
  • Strengthened Mondrian 6 adoption and cut design/dev effort for future campaigns.

// SCENE 05

Key learnings

  • Design systems become much more powerful when combined with rich business logic.
  • PLPs aren't just browsing surfaces — they're commercial storytelling tools.
  • Early engineering & commercial alignment dramatically improves quality and speed.
