If deviations and manipulations of processes of any kind are to be excluded, it is necessary to understand which factors lead to a change in acceptance. In the present paper, a large scale experimental study is carried out to investigate the influence of the number of process activities and the process throughput time on acceptance. A generic purchasing process is implemented online and executed in variants by the participants of the study. Process acceptance is measured using a questionnaire in three dimensions of attitude (cognitive, affective, conative). The analysis demonstrates that there is a significant difference in acceptance with regard to varying process throughput time as a measure of process length.enBPMProcessAcceptanceExperimentAmazon's Mechanical Turk10.18420/inf2020_561617-5468
