Success Metric

  • Clear visitor vs. registered HCP experience

  • Compliant access through HCP verification

  • Increased registration motivation

  • Scalable platform structure for future growth

Product Context & System Constraints

Daiichi Sankyo aimed to create a disease‑focused digital platform for non‑valvular atrial fibrillation (NVAF)—a chronic condition that requires continuous education, updates, and engagement from healthcare professionals.

The platform was designed exclusively for Dutch healthcare professionals (HCPs) and needed to balance:

  • Medical credibility and regulatory constraints

  • Controlled access to content (licensed doctors only)

  • Ongoing engagement through education, events, and direct communication

The Challenge

The challenge was not only to design screens, but to define a system that:

  • Differentiates access based on user type and verification

  • Supports multiple content types and interaction models

  • Integrates backend services (identity verification, email, meetings)

  • Encourages registration without blocking discovery

Work Process

Business Logic & User Flows

Working closely with the Product Owner, I translated requirements into clear system logic and visual documentation.

Deliverables:

 - Sitemap

 - Backend interaction mapping (emails, meeting tools, verification)

 - 11 detailed user flows

These flows served multiple purposes:

 - Alignment tool with the client

 - Functional blueprint for developers

 - Validation reference during testing

They documented not only user actions, but also:

 - System responses

 - Automated communication

 - Edge cases based on user type

System Thinking, Defining Users & Access

A critical early step was defining who the platform is for and how access should work.

User Types:

1. Registered HCP

  • Licensed healthcare professional in the Netherlands

  • Verified via BIG number (Dutch medical license) 

  • Full access to content, education, events, downloads, and meetings

2. Visitor

  • Any non‑registered user

  • Can explore high‑level content

  • Must register to access gated features

This distinction drove permissions, content visibility, messaging, and user flows across the entire system

Goal - Design a scalable disease platform that attracts healthcare professionals to register by:

1.

Offering trusted medical content

2.

Providing accredited education

3.

Promoting relevant medical events

4.

Enabling direct communication with medical representatives

Visitor

  • Has access to home page

  • Can access the one-on-one meeting with a representative from Daiichi

Registered HCP-health care professional

Has full access to all the website pages and features

Business Logic & User Flows

Working closely with the Product Owner, I translated requirements into clear system logic and visual documentation.

Deliverables:

  • Sitemap

  • Backend interaction mapping (emails, meeting tools, verification)

  • 11 detailed user flows

These flows served multiple purposes:

  • Alignment tool with the client

  • Functional blueprint for developers

  • Validation reference during testing

They documented not only user actions, but also:

  • System responses

  • Automated communication

  • Edge cases based on user type

User Flows

Key System Integrations

Backend connections included:

  • Email communication logic

  • Online meeting room integration

  • BIG number verification for licensed access

Each integration directly influenced UX decisions around feedback, messaging, and trust.

Wireframes & UI Logic

Open vs. Closed Experience

Open Home Page (Visitor)

  • Designed to attract healthcare professionals

  • Content is visible to build trust

  • Any interaction with content triggers registration

Closed Home Page (Registered HCP)

  • Full access to all content and features

  • Personalized messaging and clearer context

  • Direct entry points to education, events, and meetings

Although both user types see similar entry points, they follow different system flows depending on authentication status.

User Flows

User Flows

Education & Events as Engagement Drivers

Education

  • Accredited educational content allowing HCPs to earn mandatory points

  • A strong motivator for registration and repeat visits

  • Required clear UX around value, credibility, and access

Events structured into:

  • All events

  • Upcoming events (with countdown)

  • On‑demand (recorded past events)

Designed to support both real‑time participation and long‑term content value.

Impact

The final platform concept:

  • Clearly separates discovery from gated medical access

  • Supports regulatory requirements without harming usability

  • Encourages registration through real professional value

  • Scales across content, education, and events

  • Strengthens Daiichi Sankyo’s positioning as a reliable medical partner

Additional Features

Constraints & Trade‑offs

Designing a disease platform in a regulated healthcare context required balancing usability, compliance, and business goals. Several constraints directly shaped the system architecture and UX decisions.

Regulatory & Access Constraints

The platform was intended only for licensed healthcare professionals in the Netherlands.

Access to medical content and features required BIG number verification, introducing friction into the onboarding flow.

Content visibility had to be carefully managed to avoid exposing regulated information to non‑registered users.

Trade‑off:
We intentionally allowed visitors to see content previews to build trust and motivation, while gating interaction behind registration. This balanced compliance requirements with the business goal of attracting qualified HCPs.

Identity Verification vs. Conversion

BIG number verification was essential for credibility and legal compliance.

Verification added complexity and potential drop‑off during registration.

Trade‑off:
Instead of blocking discovery entirely, we designed an open home experience that communicates value early, then introduces registration only when users attempt to engage with content. This preserved conversion while maintaining controlled access.

Outcome

This project resulted in a clear, scalable system for delivering disease‑specific medical content to licensed healthcare professionals in the Netherlands.

By defining user roles, access permissions, and backend‑driven flows early, the platform:

  • Balances regulatory requirements with usability

  • Encourages registration without blocking discovery

  • Supports ongoing education, events, and direct communication

  • Establishes a foundation that can scale across future disease platforms

System Integration Dependencies

The platform depended on multiple backend integrations:

  • Email communication

  • Online meeting scheduling

  • License verification

UX decisions had to align with what backend systems could reliably support within the project timeline.

Trade‑off:
User flows were designed conservatively to ensure reliability and clarity, prioritizing predictable system behavior over more complex but fragile interactions.

Content Discoverability vs. Personalization

Visitors and registered users accessed the same platform but with different permissions.

The system needed to support shared navigation while delivering role‑appropriate experiences.

Trade‑off:
We kept a consistent structure across user types to reduce cognitive load, while differentiating messaging, access, and system responses based on authentication state rather than creating separate experiences.

Timeline & Scope Constraints

The project timeline was limited to two months.

UX work needed to support both immediate delivery and future scalability.

Trade‑off:
We focused on establishing clear business logic, user roles, and system flows as a foundation, ensuring the platform could evolve without requiring a structural redesign

The work ensured that UX decisions aligned not only with user needs, but also with business, technical, and compliance constraints.
