Healthcare Visualisation: Building a Design Function from Scratch

The Real Problem

Microbiome science has enormous potential to transform healthcare, but its complexity creates significant barriers to adoption. The company faced a critical problem: both healthcare providers and patients struggled to understand the science behind microbiome analysis. Leadership assumed the problem was acquisition and churn. I discovered something different.

Reframing Through Data

I conducted deep dives into both qualitative and quantitative data. Using Mixpanel, I personally categorised user behaviour patterns and uncovered that users exposed to educational materials had a 20% higher conversion rate. This revealed the real problem wasn't acquisition or churn, it was activation. Providers who reached an 'education saturation point' developed more effective patient conversations. The $500 out-of-pocket cost meant patients needed to be convinced, and providers couldn't explain the science well enough to do that.

• 20% higher conversion rate among users exposed to educational materials
• Provider confidence was the key lever, not marketing spend
• The $500 cost barrier meant patients needed provider advocacy, not just information
• Existing clinical reports used medical jargon inaccessible to non-specialists

The Player-Coach Model

I was the sole design resource but operated as a player-coach mentoring a 7-person cross-functional team (3 PMs, 2 engineers, marketing, social). I built the complete design function from scratch: design systems with design tokens for multi-tenant B2B white-labelling, brand guidelines, responsive frameworks across mobile and web, component libraries, user research operations, and analytics implementation across every screen, button, and interaction.

Multi-Modal Learning Framework

I designed a visualisation system using a multi-modal learning framework that addressed different learning styles. The same microbiome data was presented through multiple visual channels, each optimised for its audience.

• Provider dashboard with comparative baseline visualisations and temporal trend tracking
• Patient-facing reports with plain language and visual progress indicators
• Interactive learning environments with personalised educational paths
• Functional groupings moving beyond taxonomic classification to show bacteria's roles in health
• Accessibility-first design supporting colour-blind and low-vision users

Experience Flow Applied

I applied the Experience Flow methodology to map complete user journeys from initial pain realisation, not just product entry. This meant designing cohesive experiences across multiple touchpoints from marketing to product to retention. I established a structured research function that collected over 100 feedback points, creating a layered information architecture that balanced accessibility with depth.

Navigating Organisational Resistance

Despite presenting compelling research and data to key business leaders, I navigated significant organisational resistance to data-driven decision making. This taught me that design leadership isn't just about craft, it's about building the case for change with evidence that stakeholders can't ignore. The Mixpanel data that showed the activation gap became the wedge that shifted the product strategy.

Results

The visualisation system delivered exceptional results across every metric, demonstrating how effective data visualisation acts as a translation layer between raw information and human understanding.

• 35% increase in healthcare provider confidence through intuitive visualisation
• 42% improvement in patient understanding of complex scientific concepts
• 38% reduction in support requests through layered information architecture
• 100+ feedback points collected through structured research function
• Visualisation framework adopted as standard for all clinical reporting
• Design system with design tokens enabling white-label B2B customisation

What I Learned

The real problem is rarely what leadership assumes. Validate with data before accepting the brief. And design isn't just aesthetics, it's a driver of product-market fit and retention. When I reframed the problem from acquisition to activation, the entire product strategy shifted. That reframing came from sitting in Mixpanel for hours, personally categorising behaviour patterns, until the signal became undeniable.
