The Challenges of Designing a Scalable

Telehealth SystemErika Chuang, VSee

Questions/comments I frequently hear Video visit is fundamentally not scalable.  Does your product integrate with XYZ? Our

providers do not want to use another tool. Does your product work these equipments? We

already spent $$$ purchasing them. We want to use this telehealth vendor, but they just

can't do everything we want to do.

Platform strategy

Reusable components Fast delivery of new products Reduced development and maintenance cost Improved quality Reduced cost

Traditional model of building platforms Implemented largely before applications are built Focus primarily on the technical criteria

Performance Robustness Scalability Security

Less focus on what value they deliver to end-user Feature bloat Poor usability

Agile and user centered design

Applications are developed at the same time as the platform Works well with end-user application with known end

users and product goals Not so obvious when building a platform Multiple product teams with specific needs and goals

can cause conflicts  Some products may not even exist yet

Agility, but not stability

A scalable telehealth platform to support many user-friendly applications

How to balance between the design of platform to design of applications

How to avoid building a bloated system How to continue expand platform capability to meet

changing business goals while maintaining stability and robustness
