User flow
After gathering most of the inputs, I began mapping the user flows and the user journey.

Wireframes
The next step was creating a lo-fi prototype to start some validations with stakeholders.






Usability test
With the help of the engineering team and 2 other designers, I prepared and facilitated the first user tests, to validate our design hypothesis and usability problems.





Outcome
The main ROI of this work was marked by a notable (20%) increase in service efficiency. Furthermore, the company decided not to spend any more money on the conventional training process due to the high improvement in the learning curve of the new POS.
