Indeed, a very interesting question.
Artists - Developers relationships world is definitely polar (it has ART and MATH poles), so I, as a workflow designer tried to map this world to be able to operate with it during software using/development cycle.
My best assumption at the moment which could possibly take into account abstractions levels is a supersymmetry model of those relationships which I can schematically depict like that.
From this map it is possible to see that artists demands depends on their abstraction level.
For example, the level of a technical demands and general possibilities of a technical artists who are close to manual production are different from demands of a general compositional artists, and since they are focused mostly on a local tasks none of them are focused on general pipelines, which is a pipeline management job.
Compositional Artists are naturally farther from development abstraction level than technical artists as well, so technical artist can provide technically deeper feedback, but for a limited scope.
In short, artists are very different (by skills, technical and workflow range demands), and this probably better be taken into account.
Tell me, please, what do you think about such a map.
