Too many people are working on the same project. Usually, this harms the outcome, hurts people's feelings, and prevents things from progressing as planned.
For example, the limit of teammates on PUBG is 4, enough to lead the team to victory. A few cheaters resort to teaming up with other squads, a surefire way to win. However, things become problematic when betrayal occurs, resulting in account closure.
Large groups frequently do not serve goals, as well as smaller teams, since it is more difficult for supervisors to keep track of each team member's tasks and the resources they utilize to complete them. Greater accountability, autonomy, and flexibility are made possible by smaller teams, both in terms of scheduling and idea-based improvements. They help team members feel more trusted and less afraid to fail.
