Healthcare Dashboard Performance Optimization
Outpatient Healthcare Provider (United States)
<10s
Report Load Time
Problem
The client relied on in-house Tableau dashboards for operational and business decision-making. However, poor performance made reports largely unusable for day-to-day use.- Extremely slow dashboard load times (20+ minutes)
- Improper setup of Tableau server resulting in poor site, user management and security risks
- In-efficient data model, relationship - joins across tables and high volume of data rendered report refreshes very slow (>30 mins)
Approach
We conducted a focused Tableau performance tuning and data model optimization exercise.- Fixed data model and Tableau dashboards by re-distributing data processing to the right layer (data warehouse, aggregates, materialized views, formulae)
- Improved Tableau server setup and implemented group based security
Results
The performance tuning effort delivered immediate and measurable impact:- Dashboard load times reduced to under 10 seconds
- Improved usability of reports for Therapists, Sales and Finance teams’ decision-making
- Increased BI adoption across all teams
"Optimizing our Tableau dashboards dramatically improved performance. Reports that were previously unusable are now fast, reliable, and widely adopted."
