The app is a point-of-sales system for small shops such as this one common in emerging market countries.
 Our target audience is shopkeepers such as this man named Uriel. During user research, we asked him to pick one word that described working with wholesalers. He said dificil, which translates to "difficult." The aim of our project was to overhaul this process.
 The app is currently being used by shopkeepers across Mexico and Colombia with new pilot markets in India and Ghana. Here, a shopkeeper manually enters receipts from wholesalers into the app, a task our project aimed to make redundant.
 This is our competition: a simple accounting notebook. We worked with shopkeepers closely to study these hand written records to replicate and improve upon them in the point-of-sales system.
 I taught the product team based in Mexico a human-centred design way of working. Here, we download all of our user research findings to compile insights to form the foundation of our new features.
 As a design innovation consultant, I teach by doing and documenting how we're working to share with other teams based in Spain and Colombia.
 We test a few prototypes at different fidelities with our shopkeepers. Some prototypes are clickable on a tablet, and others are paper prototypes. The key is to build the least possible to learn the most.
 I design screens for a new ordering features are rolled out using an agile dev process in a matter of weeks. This is an automatic order put together based on sales records.
 We use many Android default styles, designing the least possible to get the first release to market as quickly as possible. The TiendaTek app is available in the Google Play Market in Mexico, Colombia, Ghana and India.
