Some of the most significant social challenges — child poverty, homelessness, climate change, indigenous health disparities — are too complex for any single organisation or funder to solve alone. Collective impact offers a framework for coordinating multiple funders, organisations, and government agencies toward shared outcomes, with a backbone organisation providing the connective tissue.
Collective impact, as described by Kania and Kramer (2011), involves five conditions for large-scale social change:
The framework emerged from case studies including the Strive Partnership (Cincinnati, focused on cradle-to-career education outcomes) and has since been applied to many social issues globally.
The backbone organisation is the organisational hub of a collective impact initiative — it does the coordination work that allows frontline organisations to focus on delivery.
Backbone functions
- Facilitating partner meetings and shared decision-making
- Collecting, analysing, and sharing data across the initiative
- Managing funder relationships and grant compliance on behalf of the initiative
- Communications — public reporting, stakeholder engagement, advocacy
- Capacity building across partner organisations
- Strategic facilitation and adaptive learning
Backbone funding
Backbone organisations are difficult to fund through traditional grant structures:
- They are not direct service providers — they don't fit easily into service delivery grant categories
- Their value is coordination, not outputs
- Backbone functions require sustained, multi-year funding
The most common funding model for backbone organisations involves:
- A mix of philanthropic funders contributing to a shared pool
- Some government contribution (particularly if government is part of the initiative)
- Membership contributions from partner organisations
- In some cases, fee-for-service from partners who benefit from backbone data and coordination
Vibrant Communities
Vibrant Communities (operating in several New Zealand cities) is a collective impact model focused on community development — bringing together councils, government agencies, business, and community organisations around shared community wellbeing goals.
Healthy Families NZ
The Ministry of Health's Healthy Families NZ initiative coordinates multiple agencies and community organisations around preventive health in selected communities — a government-led collective impact approach.
Place-based collective impact
Many New Zealand collective impact initiatives are place-based — focused on a specific community or rohe. The Whanau Ora model coordinates services and support for Māori whānau across multiple providers.
Education collective impact
Education-focused collective impact initiatives (modelled on Strive) have been piloted in New Zealand — coordinating early childhood, schools, and youth services around shared educational outcome measures.
Communities for Children
The federal government's Communities for Children programme funds backbone facilitating partners to coordinate early childhood services in disadvantaged communities — a government-funded collective impact model.
Melbourne City Mission and Partners
Multiple collective impact initiatives in Victoria coordinate homelessness, family services, and early intervention.
The Pathways Programme
Pathways models coordinate employment and training pathways for disadvantaged job seekers across multiple providers.
Place-based initiatives in remote communities
Collective impact models have been applied in remote Aboriginal and Torres Strait Islander communities — coordinating health, education, housing, and social services.
Co-funding the backbone
Multiple philanthropic funders contributing to a shared backbone fund is one of the most common funding models. This requires:
- Funders agreeing on shared outcomes and measurement
- Pooling or aligning funding cycles
- Giving the backbone sufficient autonomy to coordinate without being pulled by individual funder preferences
- Long-term commitment — collective impact takes years to show results
Aligned grant strategies
Even without formal backbone funding, funders can practice collective impact principles by:
- Coordinating with other funders in the same issue area
- Aligning reporting and measurement requirements
- Avoiding duplication of investments
- Sharing intelligence about grantee performance and sector gaps
Philanthropy networks
Philanthropy New Zealand and Philanthropy Australia provide infrastructure for funder coordination — convening funders working in shared areas, facilitating co-funding discussions, and promoting collaborative grantmaking.
Governance and power
Who decides the agenda? Collective impact can replicate or concentrate power if not designed carefully — dominant funders, government agencies, or larger organisations can crowd out community voice.
Long time horizons
Systems change takes time. Most philanthropic grants are one to three years. Collective impact requires five to ten year commitments to see results.
Shared measurement is hard
Agreeing on what to measure, how to measure it, and who owns the data is genuinely difficult across multiple organisations with different systems, capabilities, and priorities.
Backbone sustainability
Backbone organisations that serve partners can become dependent on one or two dominant funders — vulnerable to mission drift or funding withdrawal.
Community voice
Collective impact initiatives can become dominated by professional organisations and institutions, losing genuine connection to community. Centering community voice — particularly for initiatives serving marginalised communities — requires deliberate design.
Collective impact works best when:
- The problem is genuinely complex and systemic
- No single organisation can solve it alone
- Multiple sectors need to coordinate
- There is shared political will across key stakeholders
- Sustained multi-year funding is available
Collective impact may not be appropriate when:
- The community itself should lead (not coordinated by external backbone)
- The issue requires urgent response rather than long-term systems work
- Funding is short-term or uncertain
Tahua's grants management platform supports backbone organisations and collaborative funders — with multi-funder portfolio management, shared reporting dashboards, partner organisation management, and the coordination tools that help collective impact initiatives track shared outcomes across complex cross-sector partnerships.
