Start with the decision
What should a visitor understand, believe or do? An enquiry, a booking and a purchase are different outcomes. Choosing the main outcome helps establish the information and interactions that deserve priority.
Bring the content into the room
Services, pricing, project examples and useful answers are the substance of the website. Identify who supplies them, who checks them and where they need to be maintained.
Name the operational needs
A website is also a working system. Establish where enquiries go, which tools it connects to, who edits content and who takes responsibility after launch. Those answers make the scope more useful.
