decision via email

Very few organizations sanction decision via email for more than very minor decisions. Some consider it a worst practice.

The Efficient Civics Guild has studied such procedures and situations where making a decision via email may be viable. Its serious attempts to specify consensus procedures that rely wholly on any written medium tend to identify more problems than viable solutions.

The yahoogroup and opengroup and wiki technologies provide other ways to make decisions, typically by supporting some kind of vote system.
