At the heart of these is the need to give the audience the impression that the presentation is in fact a team effort, rather than a sequence of short individual presentations. Ideally, of course, a team will have worked extensively together, and members will be sufficiently well attuned to each other's skills and interests to be able to function seemingly effortlessly as a unit. In reality, however, team presentations are often essential steps in proposals for major new assignments, where teams are assembled in response to perceived needs of the prospective clients, and have not necessarily worked together extensively in the past. Don't have team members in front of the audience unless they have been introduced to the audience or will be very soon. Be sure that all team members involved in the presentation appear to be contributing significantly.
Audiences tend to be skeptical of presenters who have nothing to contribute.
When team members are presenting, be sure that other team members who are still in front of the audience continue to behave appropriately. Silence does not confer invisibility, and the audience may be distracted or distressed by inappropriate behavior. Sit or stand still, do not confer unless absolutely necessary, follow the presentation with apparent interest, and do not draw attention from speakers. Plan transitions and handovers between speakers particularly carefully. Fumbling the ball here does not create a positive image of credibility.
