Fortunately, I did not get a million responses to my request for parliamentary stories. The ones I received suggest that there is a spectrum of parliamentary behaviors. At one end, organizations do an outstanding job of learning parliamentary protocols and tolerating members while they learn At the opposite end, civility gets so out of hand that organizations are forced to disband. Fortunately, there are more organizations at the learning end than at the unruly end of the spectrum. In the middle, there appear to be a variety of parliamentary behaviors arrived at by consensus.
Members tacitly agree on the norms.
As long as everyone perceives the meetings to be fair and open, the business of the organization is conducted with common approval. The informal approach works best for small groups. It may work indefinitely but there is a danger that informality leads to contempt. To illustrate, a civic organization's Board thrived for 15 years, then a former Board member was elected President. By the third meeting, Board members were getting restive.
