The EVM site selection process and The EVM Site Selection Tool User Guide

This document describes how to choose the sites for an EVM assessment. The first

step is to collect basic data on the country’s immunization supply chain. These data

are then used to select sites in a systematic manner so that the sample is

representative of the whole supply chain; the results of the EVM assessment should

then provide a valid picture of its strengths and weaknesses. This selection process

must be done in a standardized way to ensure that results within and across

countries can be interpreted and compared in a consistent way.
