   Strategic planning is the foundation of convention organization. Managers need to define the event's objectives, including the target audience, size, duration, and budget. This involves market research, identifying potential sponsors, and setting clear goals for the convention. Strategic planning also includes selecting the right venue, considering accessibility, capacity, and facilities.
