From a sociological perspective, social norms are informal understandings that govern the behavior of members of a society. Social psychology recognizes smaller group units, such as a team or an office, may also endorse norms separately or in addition to cultural or societal expectations. In other words, norms are regarded as collective representations of acceptable group conduct as well as individual perceptions of particular group conduct. They can be viewed as cultural products (including values, customs, and traditions) which represent individuals' basic knowledge of what others do and think that they should do.
