@article {1155, title = {A Taxonomy of Factors Influencing Drop-Out Behaviour in Living Lab Field Tests}, journal = {Technology Innovation Management Review}, volume = {8}, year = {2018}, month = {05/2018}, pages = {5-21}, publisher = {Talent First Network}, address = {Ottawa}, abstract = {The concept of a {\textquotedblleft}living lab{\textquotedblright} is a relatively new research area and phenomenon that facilitates user engagement in open innovation activities. Studies on living labs show that the users{\textquoteright} motivation to participate in a field test is higher at the beginning of the project than during the rest of the test, and that participants have a tendency to drop out before completing the assigned tasks. However, the literature still lacks theories describing the phenomenon of drop-out within the area of field tests in general and living lab field tests in particular. As the first step in constructing a theoretical discourse, the aims of this study are to present an empirically derived taxonomy for the various factors that influence drop-out behaviour; to provide a definition of {\textquotedblleft}drop-out{\textquotedblright} in living lab field tests; and to understand the extent to which each of the identified items influence participant drop-out behaviour. To achieve these aims, we first extracted factors influencing drop-out behaviour in the field test from our previous studies on the topic, and then we validated the extracted results across 14 semi-structured interviews with experts in living lab field tests. Our findings show that identified reasons for dropping out can be grouped into three themes: innovation-related, process-related, and participant-related. Each theme consists of three categories with a total of 44 items. In this study, we also propose a unified definition of {\textquotedblleft}drop-out{\textquotedblright} in living lab field tests.}, keywords = {drop-out, field test, Living lab, taxonomy, user engagement, user motivation}, issn = {1927-0321}, doi = {http://doi.org/10.22215/timreview/1155}, url = {http://timreview.ca/article/1155}, author = {Abdolrasoul Habibipour and Annabel Georges and Anna St{\r a}hlbr{\"o}st and Dimitri Schuurman and Birgitta Bergvall-K{\r a}reborn} }
