For meeting and event planners, the most consistent element of their job is change. The vast majority of planners understand this, and simply expect that they will have to adapt some elements in the weeks, days and hours ahead of an event. In one segment of the meetings and events business, the medical and pharmaceutical niche, changes often come many months in advance, though. This shouldn’t make other planners envious, because these changes have huge consequences for the way a medical/pharma event must be run, the quality of the attendee experience, and the satisfaction of exhibitors and sponsors.
