Serving the needs of a specific community, standards can have significant positive effect not just for that group, but also on society as a whole. But the establishment of standards should always be weighed against the potential for improper commercial exploitation, possible barriers to change and the cost implications associated with revising an existing standard versus adopting something new. Given this, we should examine the organizations that create and maintain standards. First, there is no global standards-setting authority and no federation that coordinates all the various standards efforts. In the majority of cases, participants are volunteers with their time and effort effectively donated by individual firms for the greater good.
