The document discusses project evaluation methods for projects where monetary value cannot be measured. It focuses on the International Vaccine Institute which develops vaccines for developing countries. For projects that aim to save lives but cannot assign a monetary value, IVI asks how many lives will be saved or missed by delivering, not delivering, or delaying the project. When monetary value cannot be measured, IVI evaluates projects based on their impact in reducing disease burden, as measured through techniques like cost of illness, willingness to pay, and burden of disease studies.
