Why might slow members impact team performance?

The correct answer highlights the potential for slow members to inhibit the progress of the entire team. In a collaborative environment, the effectiveness of a team relies on the synchronization of its members' contributions. If some individuals are unable to keep up with the pace of work or decision-making, this can create bottlenecks that affect the overall workflow.

When one or more members are slow, it can stall discussions, delay the completion of tasks, and impede the team's ability to reach conclusions efficiently. This can lead to frustration among quicker members who may feel their productivity is being hindered, causing a ripple effect that diminishes the group’s overall performance.

The other options illustrate outcomes that, while valuable in certain contexts, do not directly address the primary concern of team efficiency. For instance, uplifting morale or increasing cohesion are important, but they do not mitigate the fundamental issue of slowed progress due to one or more members not keeping up. Fast decision-making is also unlikely in such a scenario; rather, it would more likely be compromised as the team spends time waiting for slower members to catch up.
