“Cross-sector partnerships across the country are working hard to achieve collective impact. Although public policymakers often share the goals of these partnerships, federal, state, and local policies too often impede rather than enhance the conditions necessary to operate collectively. Worse, some public policies explicitly prohibit the very things that collaborative partnerships need to succeed. Rigid funding models, a narrow focus on annual reporting, silos within and between agencies administering programs and funds, and inaccessible or unaligned data sets all create obstacles to achieving collective results,” write the authors of this article from SSIR. They argue that “broader adoption of public policies that encourage collaboration will require changes to government structures, accountability mechanisms, and auditing and accounting practices” and present “three approaches that policymakers can take to make government more friendly to collective impact initiatives.”
