Lojas Americanas

I led the complete redesign of the POS System of Lojas Americanas, one of the top 4 retail stores in Latin America. The brand-new application serves more than 1,700 physical stores. After almost 10 years, the POS system is still running at 100% of the stores.

The challenge

The job involved developing a minimum viable product (MVP) of the new Point of Sale (POS) system within a brief timeframe, to progressively replace the existing POS systems across the entire company.

B2W Digital hired me to research and design the new PDV for Lojas Americanas. I went to many stores several times to interview users and consumers. I worked closely with other Designers, Business Analysts and Product Managers to identify any metric that could help me identify improvements.

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.
