There are many benefits to teamwork. The most important of these have to do with increasing innovation and worker motivation. When workers are part of a team, they are more motivated. This is because they have important roles to play and because their contributions to the team are recognized. Teams also tend to bring in more inclusive decision making and planning. They let more voices be heard, which can lead to greater innovation.
Some would argue that there are drawbacks to teamwork. The main drawbacks have to do with efficiency. While teams do allow everyone's voice to be heard, they can also have unclear lines of authority and have difficulty in making decisions. If there is no clear leader in a team situation, decisions may take longer to make as team members seek consensus. This is less efficient than simply having one person make the decision.
