The problem
Before anything else: is there actually something here worth solving.
What problem, stated without mentioning the solution?
If the problem statement already names a feature, the team has skipped straight to an answer and can no longer tell whether it was the right one.
Who has this problem, specifically?
"Everyone" is not a segment. A problem that's real for a named group is testable; a problem attributed to everyone usually means nobody was asked.
Why now, rather than six months ago or six months from now?
Urgency that can't be explained is often borrowed from someone else's priority, and a plan built on borrowed urgency loses support the moment attention shifts.
What happens if nobody solves this?
If the honest answer is "not much," that's a real answer — it just means the effort belongs lower on the list than its advocates believe.
