Both types of activity require careful planning: the precise purpose must be defined; the programme must support the achievement of the objectives; participants must be selected; background material may be required; and the event must be evaluated to determine the degree to which it achieved its objectives. As with other promotional activities, consideration should be given to developing a media strategy for seminars and workshops so as to ensure that the issues discussed and the conclusions reached are widely disseminated. This may be especially important for workshops, and an advocacy and follow-up strategy may be necessary to ensure that any recommendation or advice is acted on. 67
