Final answer:
Among the presented options, related short-term and long-term goals are essential for successful teamwork. Diversity and effective communication also play significant roles in building a cohesive and productive team environment. Suppression of negative information is detrimental to trust and collaboration.
Step-by-step explanation:
Among the options provided, related short-term and long-term goals is essential for successful teamwork. When team members align on a set of goals, it provides a clear direction and ensures that everyone works towards the same outcome, fostering unity and collaboration. A large number of team members does not inherently lead to effective teamwork; in fact, smaller groups often have stronger cohesiveness. Having similar abilities and skill sets may not be beneficial, as diversity in skills can enhance a team's overall capabilities. Suppression of negative information can harm trust and communication within the team, leading to unresolved issues and weak problem-solving.
Effective teams often include members with varied skills and perspectives that complement each other. Building trust through good communication and effective negotiation skills is crucial to prevent and manage disputes. Transparency and open, clear communication ensure a more coordinated and cohesive team environment. Research including studies on gender mix in teams by Hoogendoorn, Oosterbeek, and van Praag (2013) suggests that gender-balanced teams performed better, indicating the benefits of diversity in team composition.
