Why is it important to establish expectations and guidelines when establishing any type of team or group? 5-6 sentences.

Establishing guidelines or expectations when you create a group makes it seem as if there is already a purpose to the group. adding the purpose to the group and giving it guidelines tells anyone who is lazy that this is not a lazy group and they need to go somewhere else. also establishing guidelines and expectations brings people with similar expectations and guidelines closer to the group. All of this gives you an advantage against other groups were lazy people hide and unorganization doesn't make it to the end.
