Future directions of Search & Match Service

WMDA has organised several workshops to work on the future of the Search & Match Service. During the workshops the members of the WMDA worked on:

  • Flowcharts and process flows of the end-to-end search, match and connect process
  • Description on how searches are organised within EU Member States. Including a map of the most efficient and effective search, match and connect journey and identification of opportunities and priorities for automation and streamlining (i.e. removal of redundant / non-value adding steps).
  • Explanation of the improved matching algorithm
