Name the uncertainty
“We need an app” describes a delivery format, not a problem. Start with a specific person, task and failure in the current approach. Then identify the assumption that matters: will a buyer pay, will an operator adopt the workflow or can the service fulfil the request?
Choose one complete journey
A small complete journey is more useful than disconnected screens. Follow one user from a starting point to a meaningful outcome, including validation, permissions, confirmation and recovery. Keep attractive but nonessential features in a separate list.
Define the observation before release
Agree what you will observe and what would change the next decision. A sign-up count can hide the fact that nobody completes the important task. Track genuine use, combine it with direct conversations and avoid inventing a target just because it looks persuasive.
