Abstract: In an approach to predicting and managing a collaboration delay, one or more computer processors detect a start of a first collaborative meeting. One or more computer processors identify one or more attendees of the first collaborative meeting. One or more computer processors determine a status of one or more missing participants. Based on the status, one or more computer processors predict a delay duration and a reason for a delay of at least one of the one or more missing participants. Based on the prediction, one or more computer processors determine a first reschedule recommendation for the first collaborative meeting. One or more computer processors present the first reschedule recommendation to the one or more attendees. One or more computer processors reschedule the first collaborative meeting. One or more computer processors notify the one or more attendees of the first collaborative meeting of the reschedule.
