To increase the effectiveness of a group, members should view differences as a source of _______.

Viewing differences as a source of strength is essential for enhancing the effectiveness of a group. Diverse perspectives contribute to a more comprehensive understanding of problems and foster creativity and innovation. When group members embrace each other's unique experiences, backgrounds, and viewpoints, they can collaborate more effectively, leading to well-rounded solutions that might not have been achievable within a more homogeneous group. This approach not only encourages open communication and respect among members but also helps in building a culture where everyone feels valued and empowered to contribute, ultimately leading to improved performance and group cohesion.

The other options do not capture the primary essence of utilizing differences to benefit group dynamics and productivity in the same way. While unity may suggest coming together, it does not emphasize the value of diversity in driving strength. Commitment relates more to individual dedication to the team rather than the leveraging of differences for collective benefit. Pride, although it may come from group achievements, does not specifically address the constructive use of differing perspectives.
