Defining the mission and primary outcome of a non-profit can be difficult. For there is no universal, specifically measurable bottom-line such as profit.
In his Managing the Nonprofit Organization, Peter Drucker actually provides a good measure of clarity to help overcome this challenge:
[The distinguishing feature common to nonprofits] is not that these institutions are “non-profit,” that is, that they are not businesses. It is also not that they are “non-governmental.” It is that they do something very different from either business or government. Business supplies, either goods or services. Government controls.
A business has has discharged its task when the customer buys the product, pays for it, and is satisfied with it. Government has discharged its function when its policies are effective. The “non-profit” institution neither supplies goods or services or controls. Its “product” is neither a pair of shoes nor an effective regulation. Its product is a changed human being. The non-profit institutions are human-change agents. Their “product” is a cured patient, a child that learns, a young man or woman grown into a self-respecting adult; a changed human life altogether.
