Useful starting information
What are you trying to achieve?
Useful context includes the desired result, who will use it, what exists today, any deadlines or dependencies, and the parts you are unsure about. Unknowns are allowed.
Start a project
Tell us what needs to work better.
You do not need a finished specification. Start with the outcome, the problem, what you already have and anything you know must not change.
Next phase
Guided discovery without the giant form.
A later approved site capability will support live guided questionnaires that help clients work through requirements conversationally before human review.
