This section of the Toolkit provides descriptions of various approaches to logistics system improvement implemented in particular countries. These case studies and briefs include countries' experiences using a total market approach, web-based logistics management information systems, collaboration with other countries, and supply chain integration to strengthen contraceptive security. These experiences illustrate the positive impact a successful logistics system can have on a country's health and related outcomes. Learning about what worked--and what did not-- in these countries can inform the design, assessment, and improvement of other countries' logistics systems.
