“Every company benefits from ‘the commons,’ the set of communal resources that allow firms and workers to be productive,” argue Karen Mills and Chris Rudnicki in this article for the Harvard Business Review. “Business has a key role to play in restoring America’s commons, but of course it can’t do so alone. These resources are in large part the domain of government, of educational institutions, and other community organizations. If companies want to invest in the common resources that ensure their success — and they should — they need to learn to effectively collaborate across sectors.” Mills and Rudnicki present four types of cross-sector collaboration they have observed across the United States and, building from these, chart potential avenues for business leaders to engage in such partnerships.
