Which of the following is the best way to build high team cohesiveness?

A) Decrease membership homogeneity.
B) Increase team size.
C) Build agreement on team goals.
D) Reward individual results.
E) Increase rivalry among members.

Building agreement on team goals helps to create a sense of shared purpose among team members and increases commitment to achieving those goals, ultimately leading to higher team cohesiveness. Decreasing membership homogeneity may lead to more diverse perspectives, but it can also create divisions within the team. Increasing team size may lead to more resources and expertise, but it can also make communication and coordination more difficult. Rewarding individual results and increasing rivalry among members may create a competitive environment, which can be counterproductive to building team cohesiveness.
