Team work can be more effective than individual work if the team is cooperative and well managed. It stands to reason that the work of a team of people would serve to accomplish more than work performed by only one person.
The more people who work on a project the more ideas, talents, skills, and manpower is applied to complete the project. The diversity of the workers skills enhances the project outcome and the manpower provides the ability for the project to be completed in a faster rate of time.
