group decision making

Explanation:

Group decision making happens in schools, families, groups of friends, clubs, businesses, etc. Basically every place where more than one person works, studies, lives or plays.

It involves a group of people making a decision about a common issue or problem. Since the issue or problem affects them all, the group members participate in the decision making process and they try to find a common idea or action to follow. That doesn't always happen because many times people cannot agree about different issues, but it is always better to discuss the issues that affect the group with the group itself, rather than only one person choosing for them all.
