Nonprofit organizations are tax-exempt organizations that are organized to serve the public interest rather than generate profit. They may generate revenue but must use any surplus to further their mission rather than distribute profits. Strategic planning is important for nonprofits to connect their mission and programs, establish performance measures, encourage strategic thinking about resource allocation, and define their intended impact, theory of change, strategic priorities, and resource and performance indicators. Key challenges for nonprofits include defining and measuring success, fundraising, and attracting and motivating talent given limited resources.
