Field trials are a method to study the interaction of test users with an innovation in the context of use. However, when conducting field trials, there are several reasons why users stop participating in research activities, a phenomenon labelled as attrition. In this article, we elaborate on drop-outs during field trials by analyzing three post-trial surveys of living lab field trials. Our results show that several factors related to the innovation, as well as related to the field trial setup, play a role in attrition, including the lack of added value of the innovation and the extent to which the innovation satisfies the needs and time restrictions of test users. Based on our findings, we provide practical guidelines for managers to reduce attrition during field trials.10aattrition10adrop-out10afield trial10aLiving lab10aOpen innovation10auser engagement10auser involvement1 aGeorges, Annabel1 aSchuurman, Dimitri1 aVervoort, Koen  uhttp://timreview.ca/article/959
