"Hi Andreas, thanks for the feedback. So you mention striving towards one final concept but how many "sketches, ideas and mockups" can your clients typically digest in the "very beginning"?"
"Hi Gavin, so what minimum number of concepts is your typical starting point with a client to ensure that a project is being sufficiently being explored?"
"Thanks Gary (it's been a long time) - I've always wondered about the "present only your best concept" mantra - is it more myth than reality? I've always believed that multiple concepts (but not too many....) create essential dialogue with the client."
