PSI assesses its social marketing delivery systems using MAP (Measuring Access and Perfomance) studies. They are designed to gather evidence on the coverage, quality, equity of access, and efficiency of PSI's product and service delivery systems. PSI uses this evidence to continuously improve its social marketing interventions.
MAP surveys are derived from traditional private sector distribution surveys using Lot Quality Assurance Sampling (LQAS). The main outputs are indicators of: geographic coverage (i.e. availability), quality of coverage, outlet penetration, and access. In addition, MAP studies provide information on price levels, occurence of stock-outs, reasons for not stocking a product, and other important information about a distribution network.
