FN ISI Export Format VR 1.0 PT J TI Professional Event Management for Open Air Festivals AF Achermann, Evelin AU Achermann, E AB Founded by people without background knowledge of event management the waldstock open air spektakel has continuously been developed and professionalised in a «learning by doing» attempt over the last 15 years. Today with the third generation of organisation committee the festival is still organised and staged by people without previous experiences in hosting an event of such a nature and scale. Due to this background the question arises of how professional the event could have developed and what measures could be undertaken to improve the future organisation of the festival. The purpose of the thesis is to examine the concept of professional event management and ascertain if non-specialist are able to develop a professional event concept. To guarantee more efficiency and smoothen the process of organising and realising an open air festival like the waldstock open air spektakel a tailored toolbox is developed and implemented. This additionally ensures a sound future delegation of the departments. ER
