What’s the use case?
Visit an architect. On the first visit, right after shaking your hand, she unrolls plans for a house. "Here are some sketches…"
Wait. That's backward.
Sketches for what? How do you know if I want a house or an office building? How am I to judge these plans? Is it a mind reading exercise?
The most effective way to sell the execution of an idea is to describe the use case first. And before you can do that, you need to have both the trust of your client and enough information to figure out what would delight them.
Then, describe what a great solution would do. "If we could use 10,000 square feet of space to profitably service 100 customers an hour…" or "If we built a website that could convert x percent of …" or "If we could blend a wine that would appeal to this type of diner…"
After the use case is agreed on, then feel free to share your sketches, brainstorms and mockups. At that point, the only question is, "does this execution support the use case we agreed on?"
Don't show me a project, a website, an ad buy or an essay without first telling me what it's supposed to do when it works properly. First, because I might not want that result. And second, how else am I supposed to judge if it's good or not without knowing what you're trying to do…
Too often, we're in such a hurry to show off what we'd like to build we forget to sell the notion of what we built it for.
