The IFRC has put together this document to outline a framework to make National Soceities strong. A strong National Society is one that is able to deliver country-wide, through a network of volutneer-based units, a relevant service to vulnerable people sustained for as long as needed. Being strong is an internal quality. A National Society can only become strong through its own, systematic work, led by a dedicated and convincing leadership. 

Building Strong National Societies: Our common endeavour. A comprehensive framework
