The Deutsches Mikrofinanz Institut (DMI) from Germany develops this Good Practice that focuses on early risk warning system for high-growth MFIs. As a third neutral supervisory body, DMI offers risk management and credit scoring, which are sometimes left neglected when an MFI is experiencing fast growth. This Good Practice presents and analyses a system that was developed with the help of practitioners and that was subsequently built into DMI's In-the-pro system and offered to all of its members.
