The theory of Jobs To Be Done explains that too much focus on socio-demographic data and correlations hurts companies. Rather, you have to gain a deeper understanding of your customers, who "hire" your product to help them do certain jobs under certain circumstances. For instance, you don't buy a video game console because you're male and over 30. You hire it to, e.g., do the job "connect with friends".

The chair of VSR is Prof. Dr.-Ing. Martin Gaedke, who is the primary advisor of my PhD thesis. The video… Continue reading First Screencast Published in VSR Media Center
The continuous evaluation of an e-commerce company's web applications is crucial for ensuring customer satisfaction and loyalty. Such evaluations are usually performed as split tests, i.e., the comparison of two slightly different versions of the same webpage with respect to a target metric. Usually, metrics that stakeholders are interested in include completed checkout processes, submitted… Continue reading Usability-based Split Testing or How to infer web interface usability from user interactions
Guessing the relevance of delivered search results is one of the biggest issues for today's search engines. The particular problem is that it's difficult to obtain explicit statements from users about whether they found what they were searching for. Clicks are commonly used to guess relevance (using so-called "click models") but they are far from… Continue reading StreamMyRelevance! Predicting Search Result Relevance from Streams of Interactions
