The good people at Mule Design have presented a very good run-down of how clients can make great design feedback. It’s really worthwhile because, in part, it explains that the client is not supposed to decide whether she likes any given design but, rather, is supposed to decide whether it helps her sell her widgets. The full thing is worth a careful read.
It also begs us to stop thinking of designers as “creatives”—something I must admit I’ve (inchoately) thought for some time. “Creatives” don’t want, and don’t like, feedback: they’re prima donnas. Design is a business, and it must meet business needs: otherwise it’s a pointless exercise in spending money.
In any event, we tend to be a bit more informal about presentations & feedback at ArDes: we help our clients develop a visual vocabulary, but haven’t yet needed much formal “training”. If we do, we know where to send them for it!
Edit: Changed name from “Argument from Design” to “ArDes”
