Annotation Microfinance is a double bottom line sector which is growing fast, making money and doing well in a variety of socially interesting ways. The growth of its institutions requires not only good strategies, but also good control systems and informed decision-making. All of these need an appropriate Management Information System (MIS). While a good MIS is required in any sector, the management of a double bottom line requires systems which yield information on economic, financial and social metrics. The essays in this book present the metrics required for success in this field.
