From March 14-26, inSupply held a Training of Trainers and Quantification of Health Commodities Professional Development Short Course at the University of Rwanda’s School of Public Health in Kigali. The goal of the training was to increase the participants’ knowledge and understanding of the quantification process including the forecasting and supply planning steps and how these activities contribute to commodity security. More specifically, the course aimed to strengthen participants’ abilities to (1) improve the accuracy of forecasts, (2) estimate commodity and funding requirements, (3) develop supply plans, (4) understand the utility of software packages for forecasting and supply planning, and (5) evaluate and respond to environmental or policy constraints to forecasting and supply planning. A facilitation training of trainers was held the first week, followed by the short course, which coincided with the launch of the East African Community Regional Centre of Excellence for Vaccines, Immunization and Health Supply Chain Management (EAC RCE VIHSCM). This was the second in a series of short courses that inSupply has conducted in collaboration with the University.
