Group Structure
This text explains how role identity, perception, expectations, and conflict affect norms and group behavior. It also breaks down the common classes of norms and the influences of status and group size. Finally, you will explore the different actions that the group leader can take to build cohesiveness.
Size
Does the size of a group affect its dynamics? You bet! But how size affects the group depends on where you're looking.
As a rule, smaller groups are faster than their larger counterparts. But when it comes to decision making, larger groups end up scoring higher marks. So, if there's a decision to be made, it's wise to poll a larger group . . . and then give the input to a smaller group so they can act on it.
A side note about size: groups with odd numbers of people tend to operate better than those that have an even number, as it eliminates the issue of a tie when votes are taken. Groups of five or seven tend to be an ideal size, because they're still nimble like a smaller group, but they make solid decisions like a larger group does.
