I do not know about you guys, but when I work in a team setting, sometimes things can become a little bit competitive. I always want to be in charge of putting the final project together, and making sure I receive everyone's part of the assignment at a certain point. I like how people get their job done fast because that is what I do. I never procrastinate.

"Sharing information in a cooperative effort to achieve team purpose must be more important than competing with other members for individual achievement." (Business Communication, 2016, pg.41)
This quote essentially means that you are working as a group; not by yourself. You need the support of your team to develop an excellent task/project.
During this collaboration effort, there may also be a leader assigned to your group. Now leaders are good, they keep everyone on track, and make sure people are assigned roles that best suit their strengths. A leader is often someone with the most expertise and is good at taking charge. Although having one leader is important, sometimes it is necessary to point other people as leaders. (Business Communication, 2016, pg.41) If you are working on a task where someone has more knowledge about the topic, you should let that person be the leader.
Sharing the role of leadership allows everyone to have input on the task and lets people of the group gain confidence.
