System design approach to improve the immunization supply chain


A system design approach offers a framework for analysing, designing, and implementing solutions to improve the performance of a vaccine supply chain system. However, with little information available on how the system design approach has been used, making a case for investment can be challenging. This evidence brief provides government decision-makers working in public health immunization programmes with a summary of evidence-based case studies from five country governments and one private industry. Each case study highlights the unique context, the catalyst driving the need for change, the key analysis undertaken and the results of the system design process. An overview of a system design approach and questions it can address are also provided.
