One of the strengths of the Rotary Foundation is that it has a well-developed process of evaluating humanitarian service projects. As members of the Rotary family, we invest time and skills offering hope to thousands. We do this in different ways, and all of us would like to know the impact of our efforts, which is not always easy. We also donate to worthy causes within Rotary; we know that the funds are substantial – but it is not easy to quantify or measure their impact.
