Shared Ideas
One of the main benefits of group work or a team environment is the ability to share ideas among the group. Perhaps there are several possible approaches to a project, and as an individual, a staffer may be unsure of which to take. However, as a team, the members can each contribute pros and cons of approaches to tasks and methods to accomplish key goals. This kind of collaboration both benefits the project and gives team members an outlet to bounce around ideas.

Increased Efficiency
Another key advantage of group work in the office is that things get done faster. When a group attacks a project or task, it can be done more quickly and with greater efficiency than if just one person attempted to muddle through it. A group approach can lead to cost savings for the company, since groups accomplish more, as well as an ability to meet individual and team goals more quickly, since more people are attacking the task.

Accountability for Weak Areas
Working as a team not only helps to showcase people's various strengths, but can also allow for compensation of weaker areas as well. Staffers can distribute the workload so that people are playing to their strengths with their work and team up to tackle areas where they are weaker to allow for improvement. This create a stronger and more skilled workforce, as people use the teamwork opportunity to improve across the board.

Improved Office Relationships
When people work together as a team, they not only become more invested in the project, they become more invested in one another as well. Team members support one another, even outside of the team structure, and adapt to each other's working styles. The team relationship may result in teamwork approaches even outside of the official teamwork structure, resulting in employees lending a hand on other assignments and sharing ideas or brainstorms to propel one another along to reach personal and professional goals.
