DMI Deutsches Mikrofinanz Institut e.V. (DMI), which operates in Germany, developed Accreditation Rules to ensure problem-free and efficient cooperation among German MFIs. German MFIs must comply with certain quality criteria standards, observe the Code of Honour that is based on the "Code of Good Conduct" and apply for an accreditation from DMI as a way to ensure quality assurance in the scope of the Cooperative Model, also developed by DMI, and where a deep reliance between all actors is needed.
