For a website or rebuild
Say what the site needs to explain and who will edit it. If a website already exists, give its public address and identify the part that needs replacing. Mention an existing enquiry route that must keep working.
“We need a public service website. Our current pages are difficult to update, and enquiries go to a shared inbox. We want to keep that reply route.”
Do not assume a rebuild requires replacing every connected service. The business website development outline explains how content and editing boundaries affect scope.
