Film making is in many aspects a very complex business represented by highly non-trivial business processes in which multiple organizational units are involved. Whereas in regular manufacturing and paper factories like insurance companies there is an increasing adoption of Information Technology (IT) and especially Business Process Management (BPM) technology, there is little adoption of information technology solutions in managing the collaborative aspects of film making. In this paper, the authors elaborate on the process dimension and, in particular, they focus on processes of costume management in film making.
