Gracie Salazar sells women's sportswear. She is experienced in making sales presentations to groups of two to four buyers. Gracie's sales manager has told her to prepare her presentation for a group of thirty department store buyers. Does Gracie need to make any changes in her presentation to a larger group? Explain your answer.

Yes, she needs to change her presentation. The structure used for a larger group presentation must be less flexible than the one used for the smaller groups. It would result in chaos if everyone were allowed to give feedback whenever he or she wanted to ask questions simultaneously. She needs to plan a question and answer period as a part of her presentation.
