Is "uncollaborative" a word?
I am describing a process as being antithetical to collaboration.
To clarify, I'm referring to its quality as being "not naturally collaborative", not "actively anti-collaboration"
Is "uncollaborative" a word? Is there a word that isn't a variation of "collaboration" that gets the job done?
Insular "of the nature of an island" and by extension anything which is naturally isolate (q.v.)
Independent strikes me as a good candidate.
Competitive springs to mind, if you really mean antithetical to collaboration.
