Comcast • Celestial FSM 1.5 Diagnostic — Celestial cover image

Comcast technicians relied on fragmented legacy tools to diagnose network issues. Each tool covered a narrow slice of the network stack, forcing technicians to context-switch between systems for day-to-day analysis. Average diagnosis time suffered as a result, due to workflow constraints and the absence of an intuitive tool experience.

01.
Discovery

Mapping the diagnostic landscape

Conducted a full audit on legacy tools

  • Identified dozens of critical pain points across the diagnostic flow.
  • Catalogued 4 distinct legacy diagnostic tools - Node Analysis (NA), Access Network Analyzer (ANA), Node Timeline, US Performance
  • Documented all accessibility issues that did not align with WCAG and a11y guidelines.
02.
Synthesis

Distilling signal from noise

Transformed research into actionable frameworks that would guide the platform architecture.

  • Partnered with product leadership to translate business objectives into design requirements.
  • Prioritized 8 core diagnostic workflows
  • Established the information hierarchy for real-time telemetry and diagnostic workflows.

Architecture

Designing the information backbone

Established the structural foundation that would unify 4 legacy tools into a single coherent experience.

  • Designed progressive disclosure patterns for guiding technicians through layered diagnostic workflows, surfacing context only when relevant.
  • Established unified design patterns for complex data visualizations including telemetry tables, time-series charts, performance graphs, and geospatial diagnostic maps.
  • Built new components for the network diagnostic platform that were absorbed into the company-wide UI kit.
04.
Prototyping

Building interactive proofs

Tested high-fidelity prototypes with key stakeholders and active network technicians during weekly syncs and sprint reviews.

  • Built weekly interactive prototypes in Figma
  • Collaborated with the UX research team to conduct multiple rounds of usability testing
  • Iterated on data visualization patterns
05.
AI Integration

Embedding intelligence naturally

Worked with ML engineers to integrate generative AI capabilities that felt native to the diagnostic workflow.

  • Designed conversational AI interface for diagnostics
  • Created confidence scoring UI for AI recommendations
  • Built feedback loops for model improvement

Design System

Codifying systematic consistency

Developed a comprehensive design system that would scale across the entire diagnostic platform.

  • Created 200+ component variants
  • Documented accessibility standards for field conditions
  • Defined light and dark mode color tokens meeting WCAG AA contrast across all field conditions

The most significant lesson from this next gen diagnostic tool was that enterprise AI is not about replacing human judgment. It is about amplifying it. The technicians who use this platform daily are experts. The AI serves them, not the other way around.
