In countries where the GBVIMS is implemented, there are many different ways to utilize service-based data to inform programming. These notes share the experiences of country programs using GBVIMS data for program improvement. Linking GBVIMS data analysis to programming involves looking at trends and trying to understand them in the broader context in which the violence has been reported. The data collected and stored in the GBVIMS is labeled ‘service-based’ because the data is collected at the point of and in connection with the provision of services for GBV survivors. The GBVIMS can provide one source of data to inform programming and is best used in combination with other data sources such as surveys, needs assessments, situational analyses, focus group discussions, client satisfaction surveys, and evidencebased research.
