It sounds like a simple question, but there isn't a simple answer: Why does membership matter? This week, Diane Ward, president of Membership Matters, joins in to share the ins and outs of membership programs, from data collection to evaluating who your members are. Within her work experience, she has learned how people "move in, move up and move out of membership programs." Members vote with their feet and wallets, she says, so she takes a look at why it's important to look beyond factors such as revenue and expense equations and focus on what members do for your organization.
