Which of the following can hinder group collaboration?

Lack of clear roles can significantly hinder group collaboration because it creates confusion among team members about their responsibilities and contributions to the project. When members do not have defined roles, tasks may overlap or be neglected, leading to frustration and inefficiency. This ambiguity can also erode accountability, as individuals may feel uncertain about who is responsible for what, reducing overall motivation and engagement within the group. Clear roles help ensure that everyone understands their specific duties, fostering a more organized and effective collaborative environment.

In contrast, open discussion, active participation, and frequent feedback are essential components of effective collaboration. These elements encourage communication, facilitate the sharing of ideas, and help to build trust among group members, all of which contribute to a more productive and cohesive work environment.
