Impact and sustainability of programmes are critical issues facing the development community. Heifer International has honed its approach over more than 60 years. Heifer's approach includes: use of holistic, values-based, and affirmative community development process; Heifer's Cornerstones – values and principles to guide work, including ‘passing on the gift’; and measurement of impact at three levels – values, attitudes and knowledge; living conditions; and policy and systems change.
