I think KPIs would need to be set individually for each project by a funding subcommittee. So if it was a play it would have to be X performances to Y people, etc. If it was an anthology it might have to include X Western Australian authors, and Y new authors, etc.

I think it's always important with this sort of thing to demand the recipient actually submits a report at the end of their project detailing exactly how the money was spent and what the results were.
