Author: Rolf Molich
Rolf Molich owns and manages DialogDesign, a small Danish usability consultancy that he founded in 1993. Rolf started working full-time for DialogDesign in February 1997.
Rolf conceived and coordinated the Comparative Usability Evaluation studies CUE-1, CUE-2, CUE-3, CUE-4, CUE-5, CUE-6, CUE-7, CUE-8 and CUE-9, in which more than 100 professional usability teams tested or reviewed the same applications.
Rolf was a principal investigator in the Nielsen Norman Group's large-scale usability test of 20 US e-commerce websites, involving more than 60 users.
He has worked with usability since 1984 and wrote the best-selling Danish book User Friendly Computer Systems, of which roughly 30,000 copies have been sold. The book is now available in English, with the title Usable Web Design. Rolf is also the co-inventor of the heuristic evaluation method (with Jakob Nielsen).
Rolf is an experienced speaker. His 24 tutorials at the Nielsen Norman Group World Tour attracted roughly 1,000 participants. The overall average participant evaluation of his tutorials was 4.46 on a five-point scale.
Rolf is an external lecturer at DIKU, the Department of Computer Science at the University of Copenhagen, where he teaches a Human-Computer Interaction course. From 1986 to 2011 Rolf was an external lecturer at the Technical University of Denmark (DTU), where he taught the popular Usability Engineering course.
Rolf graduated as a software engineer (M.Sc. in software engineering) from the Technical University of Denmark in 1974. From 1974 to 1997, he worked as a project manager and software methods specialist for several Danish companies.
