If you and your group are not in sync about what you want to get from and give to a group project, then you probably haven't taken the time to discuss your individual and group goals.
Goals are important to a group because they provide the group with focus and motivation.
As we accomplish our smaller or short-term goals, we are instilled with a sense of achievement and competence that motivates us to continue working toward the final product. Goals also provide a means by which group members can align themselves toward a common objective ensuring that all members know their place and role within the group and the project. Developing effective goals isn't always as easy as it may seem. Goals need to provide members with a clear understanding of exactly what steps are required to finish the project as well as the motivation to perform to the best of their abilities. If goals are too broad or impossible to carry-out, group members will become frustrated and confused.
