Usually not well.
Of course you’er going to bring inthe numbers, the spreadsheets, etc that tell the money side of the story, how this new approach is going to benefit, etc. But that’s often only part of the sale.
In my case, I think most of the problem is that for myself and some experienced co-workers, we can convey just a few sketchy details of an idea and we’re creative enough to visualize the whole thing, complete, in our heads. We have a lot of creative shorthand in our common vocabulary so we can state “A>>>Z” without having to write out all the letters in between.
The wall I keep running into is many clients outside of our creative circle plain lack this ability, they really *can’t* imagine the finished product, you have to mock up a simulation or actual example, as close to the final version as possible, before they “get it”. Any little visual discontinuities like a title card insert that says “so-and-so effect HERE”, just blows their minds. Any little perceived technical issue they come up with must have a counter-argument prepared to a fine level of detail, or they just put the blinders on and say “it’s impossible, that can never work”. And you’re done. I have had exactly that happen, down to the “it’s impossible”, only to be able to show a competitor doing exactly that impossible thing a month later, too late for us.
So often, I can’t get permission to TRY to do something until I go ahead and DO it and thus SHOW it can be done… very circular!;-) I guess this is one reason why Animatics, photomatics, pre-comps, pre-viz, etc are all so popular, because they get the creatives and non-creatives to one standardized common vision of what’s to be done. The visual equivalent of a script treatment.
So my advice to you, Frank, FWIW is to make as finished-looking of a demo as you can, however you can, and bring that to the pitch, unless you’re a really good stand-up storyteller.
The danger of this demo piece is that they may fall in love with an element in it that’s really not the most important part of the whole, and they will get really tweaked if you cut or change that later, whether your reasons are good or not. And obviously, if this is a knocked-together simulation of the final product, there’s the danger they can’t make the cognitive leap past a poor-looking element and the future one that will replace it. Some people get it just looking at the wire frame, other people have to see a final shaded render. It’s all a balancing act.
