The Center collects evaluative data from participants, users, attendees, etc. to measure how effective specific events, services, and projects were. It also calculates return-on-investment (ROI) to measure the financial value when contrasted with a for-profit event, service, or project that meets comparable criteria, with at least three samples used to calculate an average “cost” per-person or service or project cost in the market place. The basic formula the Center uses is expenses divided by per-person or overall service or project cost. This is then compared to what it would cost if profit was a consideration in the overall revenue generated. In-kind donations are also factored into the overall quality of an event, service or product. Evaluative data is also a factor in whether or not the project, service, etc. was of value to the “customer” and did it create a change in thoughts or future actions taken by the customer.
