The purpose of this guide is to provide field practitioners with a practical step-by-step process of how to plan, carry out, and update pre-crisis market mapping and analysis, leading to response/programme design and implementation as well as surveillance, early warning system (EWS), and monitoring and evaluation (M&E). The pre-crisis market mapping and analysis process included in this guidance is described as for a single agency, and the assessment and analysis team structure described herein reflects that. However, the different steps are generic and can be adapted to support inter-agency, cluster level, or other variations of pre-crisis market mapping and analysis and assessment team structures.
