A review of decision-making support tools in the water, sanitation, and hygiene sector

The authors of this analysis conducted an assessment of 120 existing support resources, including books, manuals, and websites. Additionally, we performed an in-depth evaluation of the 18 support resources that most closely resembled decision-making tools. This analysis indicated that existing support resources fail to adequately serve WASH practitioners. Most commonly missing among the resources evaluated were: an effective user interface; consideration of social implications; regional specificity; information on costs and financing; hygiene approaches; project replicability; and evaluation and monitoring.
