A corporate psychologist by training, Klaus’s passion for Usability Engineering was triggered by a serious incident that endangered the life of an unsuspecting hospital patient. In search of the cause, he found only opinions, judgmental answers, and countless rules. This led him to the question: “How can well trained, focused and dedicated professionals make mistakes that could kill someone?” The question, in turn, led him to a lifetime of research, development and now promoting the scientific principles that underpin the development of safer, more usable documentation. He founded CAT-i in 2003 and has personally trained over 6,000 professionals in 38 organizations worldwide. Born in Vienna Austria, Klaus now lives in Canada and spends his spare time on his second passion – music.
