User Experience
I care deeply about good User Experience at all times, and easily notice every detail of the customer journey that can be improved.
As much as I value data-driven research, I'm convinced that major UX decisions can be made by thoughtful design and simulation of the customer journey, leaving A/B testing only for the minor details at the very end. This is how we approach design during R&D at nuclear-physics experiments, where a missed failure scenario can cause months or years of delays and huge financial losses.
But to be successful this approach requires 3 things:
- deep understanding of the best UX practices (including behavioral, psychological, visual and technological aspects of it);
- have empathy for the user when simulating their experience with the product;
- see the big picture to address all the possible use cases and failure scenarios rather than only the most typical ones.
Equipped with both UX-design and data-research skills, I can see issues in user experience before they are shipped, avoiding frustration of actual customers.
As part of my obsession with User Experience, I'm moderating the r/fruxtration Reddit community. There I document examples of bad design that lead to frustrating user experiences.
