Measuring Nonprofit Capacity: Lessons from the OCAT and OHI Frameworks

Capacity-building is at the core of any successful nonprofit. Without the right structure, skills, and strategies in place, even the most inspiring missions can falter.

In this post, we explore two proven frameworks for measuring nonprofit capacity—the Organizational Capacity Assessment Tool (OCAT) and the Organizational Health Index (OHI)—and how nonprofits can use these tools to build a stronger foundation for sustainable impact.

Why Capacity Building is Crucial for Nonprofits

Nonprofit organizations operate in a complex environment where they must balance service delivery with fundraising, stakeholder engagement, and compliance. Strong capacity allows nonprofits to:

• Scale their programs sustainably – With robust infrastructure and processes, organizations can serve more beneficiaries without sacrificing quality.

  
  

• Attract and retain talent – High-capacity nonprofits provide clarity in roles, better training, and opportunities for growth, leading to stronger teams.

  
  

• Adapt to changing environments – From shifting donor priorities to regulatory updates, capacity ensures organizations remain agile and resilient.

  
  

Understanding the OCAT and OHI Frameworks

Both OCAT and OHI are widely recognized tools in the nonprofit sector, each with a distinct focus:

OCAT: Comprehensive Organizational Capacity Assessment

Developed by McKinsey & Company, the OCAT evaluates a nonprofit’s capacity across multiple dimensions, such as leadership, funding, governance, and infrastructure. It provides a detailed snapshot of where the organization stands and helps prioritize areas for improvement.

• Key Strength: Holistic and structured, OCAT encourages reflection and alignment among board, staff, and leadership.

  
  

• Application: Nonprofits often use OCAT during strategic planning phases to ensure their internal capacity matches their growth ambitions.

  
  

OHI: Measuring Organizational Health for Long-Term Success

The OHI, on the other hand, focuses on how well an organization operates and executes its strategy. It evaluates critical areas such as leadership effectiveness, employee motivation, and innovation. According to McKinsey’s research, organizations in the top quartile of OHI scores deliver 3x the total returns of those in the bottom quartile.

• Key Strength: Unlike OCAT, which is a static assessment, OHI emphasizes ongoing health and operational excellence, making it ideal for dynamic, fast-changing environments.

  
  

• Application: The OHI is best suited for nonprofits looking to improve execution and build a culture of continuous improvement.

Recommendations

To maximize your nonprofit’s capacity-building efforts:

• Use OCAT for foundational assessments – Begin with OCAT to establish a baseline and identify long-term capacity gaps.

  
  

• Incorporate OHI for ongoing improvement – Once foundational capacity is built, implement OHI to maintain operational health and adaptability.

  
  

• Adopt ImpacX for real-time insights – Take advantage of AI-driven tools like ImpacX to continuously measure, improve, and grow in a fast-paced environment.
