The Project Manager is an industry professional who is proficient in pre-production, operations and management of crew and gear. This person is the on-site Operations Manager and the liaison between the client and the crew. The Project Manager also interacts with venue management. The selection of a Project Manager is based on the level and difficulty of the project, i.e.: meeting-room coordinator, general-exhibit coordinator, large-exhibit-booth coordinator, or general-session-production manager. The specific roles of the Project Manager should be defined by the client, to ensure the selection of the proper individual. This position is typically supplied by the client.
