Recently, we've been experimenting with more interesting and complex ways of representing contact centre KPIs graphically in Discover. It's a fine line to tread in design because while more interesting works, more complex does not equal more good.
How KPIs are represented is the single most important factor in how efficiently that data is read and understood by the user but, in my opinion, it should look great too.
How important are wallboard and dashboard aesthetics to you? A priority, an afterthought, or something in between?
