What is great art? In the course of my work I have offered different responses: It's an expression of humanity that moves you to laughter, tears or anger; or makes you see the world differently. Or transports you out of the present moment, connecting you with the metaphysical or spiritual realm.

But in pragmatic, evidence-based public service, especially in Singapore, it can be hard for an arts administrator to articulate why a play, a musical composition or a visual artist is excellent and, consequently, why a particular project, artist or company deserves support.
