Name one way DECA promotes the development of teamwork skills.

DECA promotes the development of teamwork skills primarily through group projects and competitive team events. These activities are designed to foster collaboration among members as they work together to solve problems, create marketing plans, or develop business strategies. Engaging in team events requires participants to communicate effectively, share responsibilities, and leverage each member's strengths to achieve a common goal. This hands-on experience enhances teamwork abilities, which are crucial in both academic and professional settings.

In contrast, the other options focus on individual tasks or skills rather than fostering teamwork. For instance, assigning individual tasks and hosting solo presentations can limit collaboration, while workshops on public speaking tend to emphasize personal development rather than group dynamics.
