It's been 10 months since the start of the project when we finished the most important stage of each development - the MVP phase. Why was it important? It initiated a process of roll-out to the general public allowing us to proceed to the mass production stage.

By definition, an MVP (a minimum viable product) is like a model for the real product. It utilizes the main functionality and lets the first customers provide the necessary feedback for future development. From the economic point of view, it is much more practical to analyze the MVP insights than spending money on actual production and then discovering the probable shortcomings. The MVP stage makes it possible to eliminate those issues before the actual roll-out.

Our team conducted a presentation for our colleagues, partners, and the first customers. During the demonstration, we talked about our achievements throughout the MVP phase and showed to the public all the functions of the Ausweis service - locks creation, access sharing, revoking keys, notifications, monitoring, etc.

Basically, what we did during the MVP stage was:

• we developed native Android and iOS mobile applications;
• we conducted the necessary testing of the system;
• we implemented alarms;
• we manufactured packages;
• we prepared the product for a grand launch.

We completed the stage releasing 50 Ausweis Devices and making a full-featured multifunctional IoT mobile access service. The MVP, therefore, included a device (designed in white and black), a web cabinet and a native mobile application.
