Artistic collaboration and the completion of works of art

We present an analysis of work completion couched in terms of an effective completion decision identified by its characteristic contents and functions. In our proposal, the artist's completion decision can take a number of distinct forms, including a procedural variety referred to as an ‘extended completion decision’. In the second part of this essay, we address ourselves to the question of whether collaborative art-making projects stand as counterexamples to the proposed analysis of work completion.
