The Bill & Melinda Gates Foundation's Faecal Sludge Management (FSM) Toolbox is an open knowledge platform to enable FSM decisions across the value chain. Its analytical and situational assessment tools are designed to support city managers, private sector and donor agencies. We worked to refine the toolbox by studying four geographies and to develop end-user strategies. We did this by enhancing existing functionalities to reflect the current knowledge base in global FSM research, streamlining input data footprint required for using the tools to reflect data availability across these geographies, and improving the flow of data to enable a seamless end-user experience. We also developed detailed product uptake strategies for top stakeholders in the FSM space globally, and specifically in these geographies, by embedding it into their operating models.
