Overview

From Raw Data to Executive Strategy

Samsung Health generates terabytes of engagement data across millions of global devices. For Vice Presidents and Product Leaders at HQ, accessing this data is critical for roadmap planning. My role was to transform this raw volume into actionable intelligence. I designed a logic-driven analytics dashboard that allows stakeholders to filter complex user cohorts (e.g., 'Mobile-Only' vs. 'Wearable') without statistical errors.

Technical Constraints

Constraint: The Tableau Environment

The dashboard was built in Tableau, which offers limited flexibility for custom UI compared to React. Standard Tableau filters lacked the visual hierarchy we needed. In order to solve this technical constraints, I had to design a custom 'Global Filter' using Parameter Actions to bypass these limitations.

Before

Deep Dive: Implementing the Global Filter

By replacing standard filters with a custom Global Parameter, we forced mutually exclusive selection—eliminating the double-counting error.

THE SOLUTION

A Single Source of Truth

The new architecture unified 3 disparate reports into one master view. This optimized the reporting workflow, transforming a 48-hour manual extraction process into instant, real-time access for stakeholders.
