The Challenge

Scientific and pharmaceutical laboratories faced critical limitations with legacy sample management systems:

Technology Stack Modernization Opportunity

Pipeline Pilot–based systems provided a foundation for research workflows but had limited alignment with modern web application requirements. Updating the technology stack offered the chance to adopt contemporary frameworks, enhance support for web standards, and better meet evolving user expectations. Modernization also enables easier implementation of new features, improved maintainability, and a more flexible platform for future innovations.

Scalability Challenges and Modernization Opportunity

As laboratory operations and sample volumes grew, the existing system architecture faced limitations in handling increased data loads and concurrent users. Modernizing the architecture provides an opportunity to build a more scalable platform that can support higher throughput, accommodate expanding user bases, and maintain efficient workflows as research demands continue to grow.

User Interface Considerations

The existing user interfaces were based on older design patterns, which required significant familiarity to navigate. While functional, they did not fully incorporate modern UX/UI principles, affecting workflow efficiency and ease of use.
