The foundation for such a system is evaluation guidance that establishes standardized data elements for a variety of evaluation activit ies. The article discusses barriers to developing such a system, strategies used to deal with those barriers, the contributions made by stakeholders t o the development of the system, the end product, strategies and activities used to meet the capacity building, and technical assistance needs of stak eholders. Lessons learned from this experience should be useful to any orga nization intending to develop a large evaluation system.
