Success Story
Rapid Deployment of COVID-19 Response System
When the COVID-19 pandemic began, our team rapidly developed and deployed a comprehensive disease surveillance and response system for a regional health authority facing overwhelming case numbers.
Challenge
The client needed a complete system for case reporting, contact tracing, and resource management deployed within weeks, not months.
Solution
We leveraged our modular architecture and reusable components to rapidly assemble a tailored solution with minimal custom development.
Results
The system was deployed in just 4 weeks, processing over 10,000 cases daily and supporting 200+ field workers in their response efforts.
Implementation Timeline
Week 1: Requirements & Design
Rapid requirements gathering, system architecture design, and component selection completed.
Week 2: Core Development
Case management, contact tracing, and reporting modules developed in parallel by feature teams.
Week 3: Testing & Integration
Intensive testing, bug fixing, and integration of mobile data collection applications completed.
Week 4: Deployment & Training
System deployment, user training, and initial support provided. System went live for all users.
