National focus Groups (one for each partner country) have been formed to contribute to the process of the development of the IET. The focus Groups are comprised of invited experts and selected people from the different partner countries. The aim has been to involve potential end-users  and therefore, emergency planners, incident commanders and competent authorities from different public agencies as well as private industry and critical infrastructure providers were invited to become members of the different focus groups. These focus groups will be kept the same throughout the validation process.
