Designing based on data, not feelings
Whenever possible, I always work on the basis of facts – access statistics, user tests, interviews with users and stakeholders... In this way, all team members have a common understanding of requirements and goals without being completely dependent on personal feelings and assumptions. Especially with existing products it is easier and cheaper than ever to collect significant data.
Product development must be iterative
A digital product is never finished. On one hand, because technical development is so fast, on the other hand, because with each release new insights into users and usage can and must be gathered. The analysis of this data starts a new iteration loop and allows an improvement. Often it becomes really interesting only at the second round, because often only then you have the necessary data. Therefore I prefer a long-term cooperation with my clients.
Release faster, learn faster
I am a proponent of several smaller releases instead of one big one. Not only because users get new functions faster and get the feeling that the product is being taken care of. It's also because you gain new insights more quickly. I'm also a fan of the MVP concept.
Deep understanding of technical development
Since I also work as a frontend developer (on a small scale), I have a good, always up-to-date understanding of development processes. This enables me not only to communicate with developers, but also to realize a cost effective design process and implement hi-fi prototypes.
Focus on function with an eye for aesthetics
The most beautiful visual design is useless if the product is not understood. Nevertheless, a really good user experience also needs the appropriate visual appearance. Even though my focus is on conceptual design, I have many years of experience as a UI designer. Furthermore, I often work closely with art directors, UI and communication designers.
