Individuals that make decisions as a team work closely together as making decisions as a group and that improves motives and accomplishments and to pursue into achieving the best for all. Teams are most productive when they have a variety of people with different roles, for example, if one person had come up with good ideas and the second person showed good awareness and the third person gets the work done by the deadlines and that is what makes an effective team by decision making as a team. When the groups are bigger it gets more complicated and the slows down decision making. The bigger groups need a better structure to co-ordinate obligations to prevent repeating efforts. Smaller groups can manage to engage in important tasks. Teams are specifically good for managing with complicated and challenging tasks. It is because teamwork gives an opportunity of bringing together the techniques and ideas of each other in the team. One team member can come up with a more productive plan to manage a challenge that other members couldn’t come up with.
