There are basically two ways to get work done. One is to work individual. In this way, people can decide for them when to start to work and how to do it. What’s more, they will be able to learn how to solve the problems on their own. People may also choose to work in a team which they can learn from each other and help each other. Beside, they may work out better ways get work done by discussing. Personally, I prefer to work in a team, which offer me a chance to learn how to get along to others and to share my experience with them. As the work can be dividing among several people, it can be done efficiently. Teamwork is always importance.
