Tessan OS and the Health Hub: the product vision in prototypes

In April, seven prototypes make the vision discussable in a week. In June they become the Health Hub: a single app, the consultation that funds, prevention programs that retain.

Role: Product design and vision
Period: April to June 2026
Team: Product designer, with product leadership
Scope: Concepts, prototypes, Health Hub

Summary

Context: Tessan installs telemedicine booths, and few patients return. The vision had to link the consultation and the follow-up between two visits, without promising what the regulatory framework forbids.
My role: Design of the five concepts and the seven prototypes, then framing of the Health Hub presented to the executive committee on June 26.

Tessan OS, seven prototypes in a week

In April, a vision document cannot be discussed in a meeting, a phone you scroll can. Each prototype carries a hypothesis: trust in a permanent interlocutor, a readable health signal, continuity between booth and mobile, prevention through small missions. The April 24 review keeps them as a heading. The seven are deployed on a public test site, with a briefing sheet per prototype: audience, context, user story, test goal. Here they are, 01 to 07, each with its demo and a link to try it online. After that, everything that reads like medical advice is removed: the score becomes the Wellbeing Score, WhatsApp is dropped, “Doctor” leaves the name.

The Health Hub, a single app

On June 9, “My health” sets the rules: stable navigation, an empty state that invites, time-bound programs with a named goal and a trend-based follow-up. On June 26, the executive committee keeps a single app and an order: prevention programs, the pharmacy ecosystem, then connected devices. The vision stays a heading, conditional on the certification of the modules involved, and is not in production.
