You'll finish with: A clickable prototype from a conversation.
Showing a client a working prototype beats describing one. It also stops you building the wrong thing for six weeks.
The three screens of any flow — a job-booking example
Three screens is a flow, and a client can tell you a flow is wrong. One screen is a picture, and nobody argues with a picture.
Say plainly it's a prototype. Clients see something clickable and assume it's nearly finished. Tell them it's a drawing that happens to click, or you'll be explaining timelines later.
The point is finding out whether the flow makes sense. Three rough screens that answer that beat one polished screen that doesn't.
The client points at something and says "no, that's not how we do it". That's the prototype paying for itself before anything got built.
If all you get is "looks great", you have shown them a picture rather than a flow, or they have read it as finished work and are being polite. Say the word prototype again and ask them to talk you through booking one real job on it, out loud, start to finish.
Brand loaded once, decks briefed properly, prototypes standing in for six weeks of guessing.
