The Problem
Opaque Forecasts & Cognitive Overload
The existing workbench put a wall of data in front of fashion allocators and left them to find what mattered. Planners drilled down through layers to reach a single high alert metric, then repeated the process for the next one. In interviews they described spending most of their day documenting where a plan needed attention rather than acting on it, and asked for something that would flag problems before those problems reached the supply chain.

Research & Discovery
Understanding the problem firsthand

Field Study at Lululemon HQ
I flew to Lululemon's corporate offices to observe how fashion planners used the software day-to-day. I conducted three rounds of research, moving from broad stakeholder context to granular user behavior:
1
Business Stakeholder Interviews
2
User Interviews with fashion planners
3
Contextual Inquiry: Watching planners work inside the live system

Design Thinking Workshop
Once field data was collected, I conducted an OOUX exercise to orient objects to actions, mapping user pain points directly to interface behaviors.
This exercise helped align design, engineering, and business stakeholders around six shared design principles that would govern every decision moving forward.

7 equal-weight alert cards. Critical items share visual space with info-level notifications, scanning requires reading every card.
Severity-ranked list. CRITICAL surfaces immediately at top; INFO recedes to bottom. Count badges replace the icon + large-numeral column format.
