F r das Management von Multimediaprojekten gab es bisher keine unternehmens bergreifenden, praxistauglichen Vorgehensmodelle, die auf spezifische Probleme der Multimediabranche zugeschnitten sind. Vorgehensmodelle aus anderen Bereichen, wie etwa der Informatik, ber cksichtigen nicht das hohe Gewicht gestalterischer und wirtschaftlicher, marketingorientierter Aufgaben in Multimediaprojekten. Das vorliegende Buch leistet einen wichtigen Beitrag, die in vielen Agenturen eher noch ad hoc gef hrten Projekte besser planbar und steuerbar zu machen. Die Autorin analysiert Vorgehensweisen und Methoden, die in der Praxis zur Schaffung kreativer Multimedia-Konzepte eingesetzt werden, und entwickelt diese zu einem allgemeing ltigen Vorgehensmodell weiter. Zur Erfassung der branchen blichen Vorgehensweisen f hrte die Autorin eine empirische Untersuchung in mehreren repr sentativen Multimedia-Agenturen durch.
