We basically gave them no training or help while we were asking them to complete simple tasks like making a Sale on Credit or Registering a Rent Expense. The shopkeepers were a mix of young and old, male and female.
It was a very humbling experience. We watched in awe while they took a long time for the simplest tasks. They got stuck in numerous occasions. They didn’t understand what a lot of buttons were supposed to do. They found some of the texts misleading. All in all, a pretty shocking test for us.
The good news was that most of the confusion was due to superficial obstacles, although some core tasks had to be rebuilt from scratch. The bad news was that we had a ton of work just to get the current features to a usable level…
If that wasn’t enough, we supplemented the UX Testing with a round of Heuristic Evaluation, which made us go through a comprehensive list of best practices to detect interface problems. That uncovered another long list of interface issues.
So for the past three weeks we have been focusing on revamping the look and feel of the application. You can judge the results with the new Main Screen, we are very happy!

The exercise has proven really valuable. Now the application is clearly improved on a key aspect, as our target customers are not the most computer-savvy. And we have learned a powerful trick to keep the user in the center of our work. I can proudly congratulate the team for turning this around so well and so quickly!

As soon as we had a workable prototype of our product TiendaTek, we looked for a handful of enthusiastic and outspoken shopkeepers that could help us with their feedback and ideas. These shopkeepers have been incredibly patient with our bugs and losses of data. And they have also been tremendously beneficial shaping the end product.

Now that we are getting ready for a commercial launch, two of them have stepped forward to join our Operations team. Given their shopkeeper background and their knowledge of the application, we are sure they will be great at sales and support!

So please welcome Harby (in the picture above) and Boris (in the video below, where he shows how he uses our phone app)!
