The European Commission supports a harmonised implementation of the Smart Readiness Indicator (SRI) across the Member States (MS) who voluntarily opt to implement it. This document, is an output of the activities of the SRI support team, and aims to provide provisional guidance on the implementation of the SRI during the period when Member States may opt to conduct test phases. At a future date the European Commission may prepare formal guidance on the implementation of the SRI informed by the experience accrued during the national test phases. The current version presents guidance that draws upon the knowledge of the SRI technical support team and some experience already relayed through provisional MS testing.
