When You Think a Norm That Is Hurting the Output

When you think a norm that is hurting the output of a group to which you were recently appointed, Effective Group Discussion recommends that you

A) observe, describe the norm and its effects, and ask if other members want to change it.
B) wait until everyone discovers, as you have, that this is a harmful norm and then suggest changing it.
C) ignore it, for it will soon be changed as the group continues its development through time.
D) leave the group and find one in which you feel compatible with the norms and procedures.
E) accept it, since there is almost nothing a newcomer can do to change a continuing group's norms.
