UNHCR: the United Nations High Commissioner for Refugees needed a tool to calculate and track water and sanitation services for refugees in urgent, short term and very long term situations. 

SheShe designed and delivered a Data Visualisation Software Tool for on and offline use that integrated with the global UNHCR data and statistic systems.

The Tool had to work on a range of systems from low-end offline laptops to mobiles to mainframes.  It was primarily for use in the field: in obscure locations with little or no internet access in the middle of highly stressful situations. It is also used for tracking and reporting by the offices in Geneva and New York.
