Discovery & User Experience

Stuzo and Verizon’s first task was to visit Fresenius’ offices in Boston for a multi-day deep immersion into the medical devices, technologies, and systems that represented the entirety of the architectural components that span across the customer experience, patient experience, and practitioner experience. Together, Stuzo, Verizon, and Fresenius conducted a deep analysis of the current state of Fresenius’:

  • Device Agent (ThingWorx)
  • Connected Health Internet Gateway
  • IoT Connected Health Cloud Service
  • Data Models, Databases, and Data Warehouse
  • Integration Engine (ESB)
  • Customer Engagement Devices
  • Unity Technology Stack
  • Clinical Applications
  • SAP Implementation
Product Strategy and Design

Due Diligence, Technology Assessments, Stakeholder Interviews

Stuzo and Verizon invented a matrix to analyze product components, integrations, data models, and enterprise services against a set of IoT business requirements. The architectural evaluation included:

  • Stakeholder Alignment
  • Gantt Project Planning
  • Technology Audit with Each Discrete Component
  • Stakeholder Interviews
  • Product Requirement Analysis
  • Gap Analysis
  • Report Generation
Product Development

Stuzo’s Results

Architectural, Operational, and Technical Strategy

Stuzo and Verizon produced a high level diagram of the Fresenius IoT connected health platform (shown here with confidential information redacted) to inform stakeholders on the current state of each discrete component (meeting requirements, may not meet requirements going forward, not meeting requirements, not currently defined but should be considered).
Further, Stuzo and Verizon:

  • Mapped out a strategic timeline for Fresenius’ Digital Transformation Services Journey
  • Produced comprehensive reporting on Fresenius platforms’ design, extensibility/scalability, functional fit, deployment architecture, and technical best practices against both current and future needs
  • Identified several gaps in technology and operations which would create risk in future iteration of the Fresenius’ IoT platform
  • Identified risks in Fresenius’ design strategy and proposed tactics to mitigate via best practices in design thinking
  • Identified a key functional cross-team DevOps role that was missing from Fresenius’ current operational structure and provided recommendations for integration of the role
Product Development

Stuzo proved to be a valuable partner to Fresenius and Verizon. Their technical expertise in IoT and ability to understand the complex business workflows within Fresenius’ care solutions helped produce a thorough technical and architectural evaluation and sound technology strategy.
