A mobile website project is easier to scope when the brief describes what people need to do on a phone and what the finished site must make possible. Before approving layouts or development, record the priority tasks, content and functional requirements so the team can make design decisions against a shared plan.
Start with the tasks visitors need to complete
List the main reasons someone visits the site, such as comparing services, checking availability, reading an eligibility requirement, requesting a quote or buying a product. For each task, note the page where it begins, the information needed and the action that should follow. A short list helps the team decide what belongs near the top of a small screen.
Set the content order before choosing a layout
Identify the headings, details, images and calls to action each page needs. Decide which information must remain visible and which can sit lower on the page. Keep labels clear and specific. Do not hide essential prices, service limits, contact options or policy information behind a menu simply to make the design look shorter.
Describe how the site should adapt
Ask how navigation, columns, tables, images and buttons will change as the available screen width changes. Long forms, wide comparison tables and menus often need a deliberate mobile treatment. Provide representative content and images during design so the team can account for real lengths and edge cases instead of placeholder text.
Specify mobile interactions and content needs
Record how phone numbers, email links, booking tools, maps, payment steps and form confirmations should behave. Identify any third-party service, account access or data handoff required. If staff update pages, state what they need to edit and whether the editing controls must work from a phone or only from a desktop.
Agree on scope and acceptance criteria
Before work begins, clarify which templates, content migration, integrations, accessibility checks, analytics events, training and post-launch support are included. Define observable acceptance criteria for the key tasks, including what a successful form submission or completed order looks like. Ask who supplies content, approves changes and records defects.
A useful mobile development brief gives the designer and developer concrete constraints while leaving room to choose an appropriate implementation. It also gives the business a clear way to review the work before launch and to understand what is included in the handover.
