Final answer:
Two key behaviors observed in successful teams are effective communication and diversity in skills, particularly gender balance. These factors contribute to a team's ability to collaborate, make decisions, and maintain a positive attitude, which is reflected in the team halo effect and the Hawthorne effect.
Step-by-step explanation:
Researchers observing team dynamics and effectiveness have identified various behaviors that contribute to a team's success. Two behaviors that stand out are effective communication and diversity in the team's skill set. Effective communication allows for building trust, advancing collaborative projects, and resolving disputes. Diversity, especially gender balance as mentioned in the study by Hoogendoorn, Oosterbeek, & van Praag (2013), can enhance team performance by introducing a broad range of skills and perspectives which can improve team interactions and decision-making.
Furthermore, the team halo effect, as discussed by Naquin & Tynan (2003), indicates that successful teams may be overvalued for their achievements while failures are blamed on individuals. The Hawthorne effect also explains that individuals perform better when observed, contributing to a team's success.
Teams with a positive attitude and those who focus on attributions for success also seem to perform better. This is reflected in how we view sports teams, attributing wins to talent and hard work but attributing losses to external factors. Moreover, teams that take different philosophical approaches, whether offensive- or defensive-minded in sports, or different styles in music, can highlight the importance of having clear strategies and alignment amongst team members. This alignment and sense of shared purpose is crucial for teams to work effectively.
