Sport Bittl

Sport Bittl: Sports enthusiast crowd helps to release a webshop

Sport Bittl has been firmly established among the well-known sports shops in Munich for decades. To ensure that the Munich sports dealer can continue to fulfil its customers’ wishes at the usual level while shopping online, the shop has been redesigned at www.sport-bittl.com. Prior to the release, the new webshop needed to be tested by representatives of the target group, so Sport Bittl chose to do a crowd test with Testbirds. In the context of a so-called BugAbility™ study, the focus was to find functional bugs in the beta version of the webshop as well as to get feedback about its usability.

Visitors of real estate portals such as immowelt.de are only two or three clicks away from the apartment of their dreams – but it is also only one click to get to another portal. If the user doesn‘t like the design, the interface is not sufficiently intuitive, or the presentation is not clear enough, it is highly likely that customers will change to another provider. Markus Teschner, Head of Product Management at Immowelt AG makes clear, “that high-quality usability tests are crucial for customer loyalty.”

For example, driving a certain distance by both their car and by public transportation or by foot. In a second part the testers had to give detailed feedback about their experience by answering ten open and closed questions and in the final step they were asked to independently and exploratively search for bugs by themselves.
