wrote a number of articles for the SAP-internal User Experience Website but
closed that section in 2008.
On the walodesign Website, I republished my articles - of course without SAP specifics.
The articles appear in three categories: DAU Stories, UI Design Thoughts und UI Design Issues.
In addition, I copublished my UI Design Blink blog articles (2010, 2011, 2012, 2013) there (slightly adapted).
