The objectives formulated above shall be accomplished by means of modern communication media such as information technology and communication networks and by the organisation of workshops. Specific objectives will be formulated from time to time, and these will be undertaken as discrete tasks either by project sub-groups or by separate project groups which may or may not include members of the working group. The working group will identify objectives for pursuance by project groups. If a project group is independent of the working group (i.e. has proposed an objective independently) then the project group should ordinarily include (a) member(s) of the working group in order to qualify for the support of the working group. Written approval is required for a project to qualify for the sponsorship of the IGUR. The IGUR will apply to the JCUS for written approval of projects.
