Covid Test


See here how just one product discovery session can turn an unfeasible product idea into a concrete, easy-to-implement MVP. It all started with a request from a concert promoter friend looking for a developer for a very concrete app idea. This app should help perform a rapid Corona test of a crowd just before starting an event. The basic idea was described as follows:

A man comes to the concert. 1. First, his ticket is validated ︎︎︎ 2. Then he is tested for Corona ︎︎︎ 3. His Ticket ID is scanned ︎︎︎ 4. ... and connected with his Corona test kit ︎︎︎ 5. While the concert visitor waits, the test results are entered into the database ︎︎︎ 6. after that, the ticket-id is sent to the concert provider to extract the phone number ︎︎︎ 7. The test result is sent to the tested person via SMS ︎︎︎




The most critical part of the idea is the request to the concert operator. First, there are not only one, but four big concert operators. And to retrieve sensitive customer data from all of them and use it in a DSGVO-compliant way will be a big challenge. We asked ourselves what the MVP could be and came up with the following idea:


What if we do it without the SMS notification service? ︎︎︎ Since we know the Corona test result for each ticket-holder ︎︎︎ We can scan tickets when visitors reenter the event ︎︎︎ and the app will display the test result ︎︎︎

The significant advantage of this flow is that all information is being stored locally and anonymously. Also, besides a simple temporal database, there is no backend or API involved. It is not even necessary to build a native app; the app can also run as a web application.
