The Readiness Index is a measurement tool used to assess the preparedness of a country or organization to respond to various challenges, such as natural disasters or public health emergencies. It evaluates factors like infrastructure, resources, and response capabilities, providing a clear picture of how ready a system is to handle crises. This index often incorporates data from various sources, including government reports and international organizations like the World Health Organization. By analyzing these elements, the Readiness Index helps identify strengths and weaknesses, guiding improvements in emergency planning and response strategies.
