“This is the final version of my recommendations for usability in product development practice, based on a PhD research project at the Faculty of Industrial Design Engineering of TU Delft. In the 25 recommendations I discuss how I would organize a company if the goal is to make usable products. So am I speculating here? Yes, to some extent. But the recommendations are based on evidence I found through the three case studies I conducted. The vast majority of the recommendations were based on actual practices within companies I studied or on suggestions by experienced product development professionals.” (Jasper van Kuik ~ uselog)
