Because of the interactive and discursive nature of the conference, we will have to restrict the number of attendees. Actually, it is more than that. We are restricted to no more than 50 people since the conference room simply cannot accommodate any more. Attendance at ICOIS’2019 is therefore by invitation only. Given the restricted number of places available, the organizers want to ensure that workshop participants are experienced researchers in the field of (Out)sourcing.
