There are as many different approaches to artistic collaboration theory as there are authors who have created them. This paper postulates that collaboration is a stage of the artistic co-creative group-work process. Theories of collaboration were examined to isolate verbiage used in various attempted definitions of artistic collaboration. Two theories were selected to serve as a joint model for the creation and maintenance of a collaboration stage during the artistic co-creative group-work process including a derived series of conditions required for a co-creative initial stage to qualify as collaboration. Those conditions were then applied to five collaborative situations to determine if each situation had established a collaboration stage, how that establishment occurred, if that collaborative atmosphere was maintained over the life of the co-creative process, how the presentational outcome of the group-work was affected by the presence or lack of a collaboration stage, and finally this collaborator’s general reactions to the process.
