What is the best reason a team might not be effective?

When a team member focuses on individual needs rather than the team's needs, it can significantly hinder the effectiveness of the group. This behavior can lead to a lack of collaboration, as the individual's priorities may conflict with the collective goals of the team. Effective teamwork relies on cooperation, shared objectives, and mutual support. When one member prioritizes personal ambitions, it can create discord, reduce morale, and prevent the team from functioning as a cohesive unit. This ultimately disrupts the collaborative process necessary for successful outcomes.

In contrast, the other options such as equal participation, frequent communication, and a clear division of tasks contribute positively to team dynamics. Engaging all members equally and ensuring open lines of communication fosters an inclusive environment where everyone feels valued and can contribute their skills effectively. A well-defined division of tasks promotes accountability and lets team members focus on their specific roles, all of which enhance overall team performance.
