How a nonprofit is usually structured
Nonprofits are governed by a volunteer board of directors that hires the executive director. Under the ED sit program teams, development (fundraising) and operations. Volunteers are often shown as a group under the program they support.
Governance is part of the chart
Unlike most companies, a nonprofit chart usually shows the board, because funders and grant applications ask how the organisation is governed.
Volunteers
Group volunteers under a coordinator rather than listing every name. That keeps the chart readable and shows who supports them.
